Perception of stress and the mechanisms of molecular chaperones
Molecular chaperones are proteins that assist the (un)folding of other proteins in the cell. Chaperones assist the initial proper folding of newly synthesized proteins and serve as active components in the translocation of proteins between cellular compartments, as well as in the signal transduction. Many molecular chaperones are stress-induced proteins (HSPs). During and following stress, such as heat-shock, they are involved in the prevention of protein misfolding and aggregation in the cell. Some chaperones can also actively unfold and solubilize protein aggregates and assist in their proper refolding or in their degradation by proteases. Hence, the chaperone network provides central mechanisms for the protection and the recovery from stress-induced damaged proteins, in simple prokaryotes, as well as in complex eukaryotes. We are also interested in the mechanism for perception of heat-stress by organisms as diverse as bacteria and higher plants.
Our long-term goal is to understand the chaperone network in bacteria, plant and human, in order to better prevent protein misfolding and promote the active curing of toxic protein aggregates in bacteria, plants, and especially in the case of protein misfolding diseases in mammals. As model organisms we use enterobacteria, cyanobacteria, the moss Physcomitrella patens and the higher plant Arabidopsis thaliana. Our experimental approaches combine genetics, biochemistry and biophysics.
1. What is the molecular mechanism by which HSP110s potentiates HSP70s in their ability to solubilize stable protein aggregates?
Background: In aging mammals, various protein aggregates can cause tissue degeneration, as in Huntington and Parkinson diseases. To maintain protein homeostasis, all organisms house a network of chaperones and co-chaperones that can effectively maintain, at least in youth, low levels of harmful protein conformers below toxicity thresholds. The HSP70s, serve as the core of the network. In Mammals, it constitutes 1% of the total cellular proteome. Hsp70 can use ATP to forcefully unfold potentially toxic aggregates and revert them into harmless functional proteins. In bacteria, HSP70 forms together with a member of the AAA+ protein family, HSP100 (ClpB), a disaggregating machinery, whose mechanism is rather well-characterized. In contrast, animal cells don’t express bona fide HSP100s. Rather, a completely different type of disaggregating co-chaperone, named HSP110, which stemmed out of the HSP70s tree in the first eukaryotes, forms together with HSP70, a completely different disaggregating machinery that too can solubilize protein aggregates, albeit by mechanism that is currently unknown. Despite clear sequence and structure homologies with HSP70, HSP110 is generally thought to lack chaperone activity of its own, and serve as a nucleotide exchange factor (NEF), merely accelerating ADP release from HSP70. How, assisted by DNAJ, may the HSP70s and HSP110s precisely identify, bind and use ATP to unfold and solubilize stable aggregated substrates? This remains unclear and is a matter of great scientific interest. Both bacterial ClpB-based and HSP110-based disaggregating machineries co-exist in the cytosol of plants and fungi, implying that the two machines unlikely process the same types of aggregates, and complement each other by processing the resistant species of the other. We have expressed and purified the major components of the yeast cytosolic chaperone network: HSP100 (HSP104), HSP70s (SSA1, SSA2), DNAJ co-chaperones (SIS1, YDJ1) and the NEFs HSP110s (SSE1, SSE2, FES1), as well as HSP90 and HSP26. We have set effective in vitro assays for ATP ase and chaperone-mediated disaggregation and reactivation of stable protein aggregates and are currently using various biophysical and biochemical methods to decipher the role of each component in the chaperone network of the yeast cytosol.
Objectives: We are currently focusing on deciphering the molecular mechanism by which the HSP110 (yeast SSE1), acts upon HSP70 and how both can, effectively target, unfold and solubilize stable protein aggregates, leading to the native refolding of toxic aggregated species. Our objective is to use methods of molecular biology, biochemistry, directed molecular evolution and synthetic biology, to revert, stepwise, HSP110 to its earliest evolutionary stage, when in the first eukaryote about 2 billion years ago, it just became an effective disaggregating co-chaperone of HSP70s, while still keeping some of its original bona fide unfolding activity from its HSP70 ancestors. Our long-term objective is to understand the spectrum of action, the potential, as well as the limitations, of the HSP110-HSP70 disaggregation machineries, in order to better understand how metazoans that lost the other bacterial disaggregating machinery, may specially suffer from degenerative conditions, such as aging and age-related neurodegenerative diseases. I plan to apply for a grant from the Israel Science Foundation on this subject.
2. Is Hsp70 recruited to re-potentiate heat-depolarized calcium channels in the plasma membranes of plants?
Background: Specific cyclic nucleotide gated channels (CNGCs) in the plasma membrane of higher plants act as plant thermo-sensors (Finka et al., 2012). The land plant CNGC2 contains a C-terminal cytosolic domain that can bind calmodulins and cyclic nucleotides. Upon an abrupt temperature increase, the closed channel readily opens to allow transient entry of extracellular Ca2+ ions into the cytosol, in turn activating the bound calmodulin(s) and initiating a specific signal cascade to overproduce heat-shock proteins (HSPs). Many HSPs act as molecular chaperones that can protect and repair structurally heat-damaged proteins. Yet, within minutes, the heat-depolarized channels become hermetically closed again, stopping heat-signals for more HSP production, despite an ongoing heat-stress. Up to five hours back at low temperatures are needed for plants to fully re-potentiate their heat-depolarized CNGCs and effectively produce more heat-shock proteins. Using the C-terminal cytosolic domain of CNGC2 as bait, we have recently identified in a yeast-two-hybrid screen a unique plant DNAJC protein. DNAJ co-chaperones generally target the HSP70 chaperone onto protein complexes that need to become converted into structurally different complexes. Like HSP60s, HSP70s can inject energy from ATP hydrolysis to convey, even under non-equilibrium conditions, stable misfolded proteins up a free energy landscape, and transiently convert them into a less stable native state (De Los Rios and Goloubinoff, 2016). We thus hypothesize that at non-heat-shock temperatures, this specific DNAJC is recruiting HSP70 onto the relaxed heat-depolarized, closed CNGC2, to use the energy of ATP hydrolysis to re-potentiate them into a different “tensed” closed state with a higher free energy, poised to readily respond to the next upcoming heat-shock.
Objectives: The long-term objective of this project is to decipher the mechanism by which the plant heat-sensory CNGCs, once depolarised by heat, may become tensed again after heat stress by the combined action of DNAJC and HSP70. We are using targeted CRISPR-mediated mutagenesis to knockout, as well as to cause the over expression of the DNAJC gene, in the model land plant Arabidopsis thaliana. We are also undertaking a Bioluminescence Resonance Energy Transfer (BRET) approach in an attempt to visualize in vivo the recruitment of HSP70 to the CNGCs after the heat-stress and the conditional interaction of DNAJC with the CNGC and with the recruited HSP70 molecules. We are also applying various biochemical and biophysical methods and we purified the DNAJC, aiming to determine its structure by X-ray crystallography and to decipher in vitro the precise molecular mechanism by which the DNAJC-recruited HSP70s onto the CNGCs can effectively use the energy of ATP hydrolysis for the transient stabilization of the tensed conformation of the channel, rendering it poised to readily respond to a next upcoming heat-shock. Because it is not known how related calcium channels in animals, such as the TRPVs, which similarly respond to heat-stress and signal for HSP accumulation, become re-polarized after the stress, this research may have important long-term biomedical implications.
