Supplementary information

The heat shock cognate 70 (Hsc70) protein also known as HSPA8 plays an important role in chaperone-mediated cellular processes. It exhibits a molecular weight of approximately 70 kDa. Hsc70 is abundantly expressed in various tissues and organs including the brain muscle and liver. As a member of the heat shock protein family Hsc70 maintains protein homeostasis by preventing protein aggregation and assisting in protein folding.
Biological function summary

Hsc70 participates in several processes beyond protein folding. This includes its involvement in the transport of proteins across cellular membranes and the degradation of misfolded proteins. Hsc70 often works in conjunction with co-chaperones and forms part of large protein complexes such as the chaperone machinery involved in clathrin-mediated endocytosis. It also plays a part in cellular stress responses supporting cell survival under various stress conditions.

Pathways

Hsc70 integrates into fundamental cellular pathways such as the ubiquitin-proteasome system and the ER-associated degradation pathway. These pathways are important for protein quality control where Hsc70 collaborates with other heat shock proteins like Hsp40 to facilitate the correct folding and clearance of proteins. In the context of autophagy Hsc70 mediates the recognition and trafficking of specific substrates to lysosomes for degradation demonstrating its importance in maintaining cellular health through these pathways.

Hsc70 shows a strong connection to neurodegenerative diseases and cancer. Misregulation of Hsc70 activity can result in protein aggregation seen in disorders such as Parkinson's disease. This situation often links Hsc70 to proteins like alpha-synuclein which accumulate abnormally in these diseases. In cancer altered expression of Hsc70 can promote tumor development by hyper-accommodating the stress conditions within the tumor microenvironment. Hsc70's interplay with proteins such as p53 highlights its role in the pathology of tumorigenesis.

Target data

Molecular chaperone implicated in a wide variety of cellular processes, including protection of the proteome from stress, folding and transport of newly synthesized polypeptides, chaperone-mediated autophagy, activation of proteolysis of misfolded proteins, formation and dissociation of protein complexes, and antigen presentation. Plays a pivotal role in the protein quality control system, ensuring the correct folding of proteins, the re-folding of misfolded proteins and controlling the targeting of proteins for subsequent degradation (PubMed : 21148293, PubMed : 21150129, PubMed : 23018488, PubMed : 24732912, PubMed : 27916661, PubMed : 2799391, PubMed : 36586411). This is achieved through cycles of ATP binding, ATP hydrolysis and ADP release, mediated by co-chaperones (PubMed : 12526792, PubMed : 21148293, PubMed : 21150129, PubMed : 23018488, PubMed : 24732912, PubMed : 27916661). The co-chaperones have been shown to not only regulate different steps of the ATPase cycle of HSP70, but they also have an individual specificity such that one co-chaperone may promote folding of a substrate while another may promote degradation (PubMed : 12526792, PubMed : 21148293, PubMed : 21150129, PubMed : 23018488, PubMed : 24732912, PubMed : 27916661). The affinity of HSP70 for polypeptides is regulated by its nucleotide bound state. In the ATP-bound form, it has a low affinity for substrate proteins. However, upon hydrolysis of the ATP to ADP, it undergoes a conformational change that increases its affinity for substrate proteins. HSP70 goes through repeated cycles of ATP hydrolysis and nucleotide exchange, which permits cycles of substrate binding and release. The HSP70-associated co-chaperones are of three types : J-domain co-chaperones HSP40s (stimulate ATPase hydrolysis by HSP70), the nucleotide exchange factors (NEF) such as BAG1/2/3 (facilitate conversion of HSP70 from the ADP-bound to the ATP-bound state thereby promoting substrate release), and the TPR domain chaperones such as HOPX and STUB1 (PubMed : 24121476, PubMed : 24318877, PubMed : 26865365, PubMed : 27474739). Plays a critical role in mitochondrial import, delivers preproteins to the mitochondrial import receptor TOMM70 (PubMed : 12526792). Acts as a repressor of transcriptional activation. Inhibits the transcriptional coactivator activity of CITED1 on Smad-mediated transcription. Component of the PRP19-CDC5L complex that forms an integral part of the spliceosome and is required for activating pre-mRNA splicing. May have a scaffolding role in the spliceosome assembly as it contacts all other components of the core complex. Binds bacterial lipopolysaccharide (LPS) and mediates LPS-induced inflammatory response, including TNF secretion by monocytes (PubMed : 10722728, PubMed : 11276205). Substrate recognition component in chaperone-mediated autophagy (CMA), a selective protein degradation process that mediates degradation of proteins with a -KFERQ motif : HSPA8/HSC70 specifically recognizes and binds cytosolic proteins bearing a -KFERQ motif and promotes their recruitment to the surface of the lysosome where they bind to lysosomal protein LAMP2 (PubMed : 11559757, PubMed : 2799391, PubMed : 36586411). KFERQ motif-containing proteins are eventually transported into the lysosomal lumen where they are degraded (PubMed : 11559757, PubMed : 2799391, PubMed : 36586411). In conjunction with LAMP2, facilitates MHC class II presentation of cytoplasmic antigens by guiding antigens to the lysosomal membrane for interaction with LAMP2 which then elicits MHC class II presentation of peptides to the cell membrane (PubMed : 15894275). Participates in the ER-associated degradation (ERAD) quality control pathway in conjunction with J domain-containing co-chaperones and the E3 ligase STUB1 (PubMed : 23990462). It is recruited to clathrin-coated vesicles through its interaction with DNAJC6 leading to activation of HSPA8/HSC70 ATPase activity and therefore uncoating of clathrin-coated vesicles (By similarity).
