Extra Details:
Molecular chaperone implicated in a wide variety of cellular processes; including protection of the proteome from stress; folding and transport of newly synthesized polypeptides; activation of proteolysis of misfolded proteins and the formation and dissociation of protein complexes. 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:21150129; PubMed:21148293; PubMed:24732912; PubMed:27916661; PubMed:23018488). This is achieved through cycles of ATP binding; ATP hydrolysis and ADP release; mediated by co-chaperones (PubMed:21150129; PubMed:21148293; PubMed:24732912; PubMed:27916661; PubMed:23018488). 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:21150129; PubMed:21148293; PubMed:24732912; PubMed:27916661; PubMed:23018488). 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:24318877; PubMed:27474739; PubMed:24121476; PubMed:26865365). 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). 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).
