Research Interests


The Kupiec laboratory uses “the awesome power of yeast genetics” to investigate basic universal processes that are very hard to study in other organisms. Our basic methodology involves Molecular Biology techniques. As yeast is today the best understood eukaryotic organism, with more than half of its genes with a known function/activity, the new genetic and molecular tools developed in yeast have jump-started a REVOLUTION IN BIOLOGY: Systems Biology. We are able, for the first time, to ask very basic questions about the way genomes are organized, genes interact, proteins talk to each other, etc. This genome-wide approach requires novel tools, which we are helping to develop in cooperation with people from Computer Science at TAU. Most of the essential pathways, complexes and genes involved in basic cellular processes are conserved in evolution, and human orthologs are present for most of the genes we study.

Here are some of the basic biological questions that we are trying to understand, using the baker’s yeast (Saccharomyces cerevisiae) and fission yeast (Schizosaccharomyces pombe) as a model organisms:

1) DNA repair:
Our cells are constantly exposed to radiation and chemicals that cause damage to the DNA or even break the chromosomes in pieces. Even natural cellular metabolism creates oxidative stress and DNA damage. Luckily we have efficient mechanisms to repair the damage. Some of the questions we ask are:

• What do you do when you break one of your chromosomes? Is it possible to heal it? (Hint: yes). How is it done? Who does it? How are these processes regulated?
• Checkpoints: How do cell coordinate different events? Do cells really stop in the cell cycle “until DNA is repaired” and then continue? (Hint: no).
• Molecular biology of genes involved in DNA repair and cell cycle in yeast.
• Dissection of the mechanism of homologous recombination: Does recombination occur between homologous sequences at different genomic locations? (Hint: yes.). Then, how do you recognize a homologous sequence in the genome? Is there a molecular mechanism that “reads” the genome?

• How does the tethering of chromosomes to the nuclear envelope affect the ability of broken chromosomes to search for their “partners” for recombination? And HOW do you SEARCH for partners with similar sequences?
• What is the minimal length required for efficient ectopic homologous recombination? (Hint: very little!)


2) Stability of the eukaryotic genome:
Normal cells have remarkably stable karyotypes. You can easily identify to what species a cell belongs, just by looking at its chromosomes. However, cancer cells lose this stability, and start accumulating translocations, deletions, amplifications, etc. Many of the endpoints of these rearrangements fall in repeated sequences (sometimes called “junk DNA”) that fill-up our genomes. What prevents a high level of chromosomal aberrations as a consequence of recombination between repeated sequences?

Using a screen for mutants with high levels of recombination between repeats, we identified ELG1 (enhanced Levels of Genomic instability). Mutants in this gene hyper-recombine, lose chromosomes, have elongated telomeres, hyper-silencing in heterochromatic regions, etc. The Elg1 protein looks very similar to the large subunit of Replication Factor C (RFC), the clamp-loader in charge of loading PCNA onto DNA. PCNA is a clamp: a ring that circles DNA and holds polymerases in place so that their processivity is enhanced. RFC opens PCNA, so that it can encircle DNA, and then closes PCNA, at the expense of ATP. RFC is composed of a large subunit Rfc1 and 4 small subunits Rfc2-5. We have found 3 additional clamp loaders. All share the 4 small subunits, but in each case a different “brain protein” replaces Rfc1: Elg1, Ctf18 and Rad24. While Rad24 was found to load a PCNA-like clamp called 9-1-1 involved in damage sensing and checkpoint response initiation, Elg1 and Ctf18 have still uncharacterized functions. Here are some of the questions we are investigating about Elg1:

What is the function of Elg1? Does it load (or unload) PCNA or another clamp? When is it needed? When are the other complexes needed? Why does Elg1 interact with Ubiquitin and SUMO-processing enzymes? What are its connections to the other clamp loaders and to different repair mechanisms? What are its connections to chromatin deposition and silencing? What are its connections to DNA replication? What are its connections to telomere maintenance? Is the human ortholog involved in cancer?

The mammalian copy of ELG1 has been found to be involved in Fanconi Anemia, a cancer-promoting hereditary human disease and in sporadic cancer. In mice, KO of ELG1 leads to tumors. What can we learn about cancer-preventing mechanisms by analyzing Elg1? Is it involved in a Fanconi-like mechanism in yeast? (Hint: yes!)


3) Telomeres:
Telomeres are nucleoprotein complexes at the end of the eukaryotic chromosomes. In nearly all eukaryotes examined, the telomeric DNA consists of tracts of tandemly repeated sequences whose overall length is highly regulated. Telomeres are essential for chromosomal stability and integrity, as they prevent chromosome ends from being recognized as double strand breaks. Telomeric DNA is synthesized by the enzyme telomerase, which copies a short template sequence within its own RNA moiety. Telomerase is expressed at the early stages of development, but not in somatic cells. Conventional DNA polymerases are unable to replicate the very ends of chromosomes due to their primer dependency. As a result, telomeres of all differentiated somatic cells and tissues shorten with replicative age in vitro and donor age. Erosion of telomeric sequences eventually leads to the disappearance of the protective structure that caps telomeres, resulting in cells entering a non replicative state called senescence. Reactivation of telomerase in cultured cells results in extended life span leading to their immortalization. Thus, telomere shortening acts as a tumor suppressive mechanism. Moreover, it has been shown that replenishing telomeres by an activated telomerase is one of the few essential steps that a normal human fibroblast cell must take on its route to become malignant. Thus, understanding how telomere length is monitored has significant medical implications especially in the fields of aging and cancer.

In cells in which telomerase is expressed, telomeres do not grow increasingly longer and longer. An intricate regulation maintains the final telomere size. Some genes facilitate telomerase activity, whereas other restrict its activity and even degrade the telomeric DNA. We would like to understand what are the mechanisms that control telomeric length in yeast. Two systematic screens, using collections of yeast mutants, resulted in the identification of ~400 genes that affect telomere length. Mutations in half of them cause telomere shortening, whereas mutations in the others cause telomere elongation. This large collection contains genes of a variety of activity and cellular location.
We would like to know how do all these genes work together to regulate telomere length. Are there several pathways? Complexes? What are the interactions between the various elements? To answer these questions we are using a combination of Molecular Biology, Systems Biology, Genetics and Biochemistry. Bioinformatic models are used as a basis to plan possible experiments. The results are then incorporated into the model, to generate more predictions in a continuous cycle that progressively refines the model.

Recently, we have found that environmental stresses and signals can also affect telomere length. Since we have, for the first time, the list of all genes affecting a complex trait (telomere length) AND a list of environmental factors affecting the same trait, we are in a perfect position to study the interphase between nature and nurture (genome and environment), a central question in Biology that could not be addressed molecularly up to now.

4) The TOR protein kinase:
The TOR protein kinases exhibit a conserved role in regulating cellular growth and proliferation. In mammals, mTOR is negatively regulated by the TSC1–TSC2 heterodimer. Mutations in either TSC1 or TSC2 cause a human syndrome, known as tuberous sclerosis complex (TSC), which is characterized by benign tumors and severe neurological defects. TSC2 encodes a GTPase-activating protein (GAP)
and together with TSC1 converts the small GTPase Rheb into its GDP-bound inactive form. Rheb binds mTOR and positively regulates its activity. In the fission yeast two TOR homologs are present. tor1 is required for starvation and stress responses, while tor2 is essential. Tor2 depleted cells show a phenotype very similar to that of wild-type cells starved for nitrogen, including arrest at the G1 phase of the cell cycle, induction of nitrogen-starvation-specific genes, and entrance into the sexual development pathway. The phenotype of tor2 mutants is in a striking contrast to the failure of tor1 mutants to initiate sexual development or arrest in G1 under nitrogen starvation conditions. Like in higher eukaryotes, the Tsc1-2 complex negatively regulates Tor2 in fission yeast. In contrast, the Tsc1-2 complex and Tor1 appear to work in parallel, both positively regulating amino acid uptake through the control of expression of amino acid permeases. Additionally, either Tsc1/2 or Tor1 are required for growth on a poor nitrogen source such as proline. Mutants lacking Tsc1 or Tsc2 are highly sensitive to the drug rapamycin under poor nitrogen conditions, suggesting that the function of Tor1 under such conditions is sensitive to rapamycin.

We would like to answer some of the following questions: What is the function of each of the Tor proteins? What is the nature of their interactions? How are they regulated? Why are mammalian cells and budding yeast so affected by rapamycin (an anticancer drug in clinical trials), whereas fission yeast can grow in its presence? How do the Tor proteins integrate signals from the environment to know when to grow? And how do they talk to the cell cycle machinery to coordinate growth (in volume) with cell division?



• How is the genome organized? Are genes randomly distributed? (Hint: no!)
• Does a deletion of one gene affect the expression of its neighbor? And if so, is this important for our conclusions about genetic phenotypes and interactions? (Hint: yes!)

• Can we use our knowledge about homologous recombination to improve Gene Therapy methodologies? (Hint: yes!)
• How is translation regulated? Is the codon usage randomly organized? (Hint: no!)
• Does the response to DNA damage occur only at the RNA level? (Hint: no, it also affects translation!)
• QTLs: Can we map all the genes affecting single traits? How do genes interact to establish a certain phenotype? (Hint: it’s complicated!)
