Conserved Site

Heat shock protein 70, conserved site (IPR018181)

Short name: Heat_shock_70_CS


Heat shock proteins, Hsp70 chaperones help to fold many proteins. Hsp70 assisted folding involves repeated cycles of substrate binding and release. Hsp70 activity is ATP dependent. Hsp70 proteins are made up of two regions: the amino terminus is the ATPase domain and the carboxyl terminus is the substrate binding region [PMID: 9476895].

Hsp70 proteins have an average molecular weight of 70 kDa [PMID: 2686623, PMID: 2944601, PMID: 3282176]. In most species,there are many proteins that belong to the hsp70 family. Some of these are only expressed under stress conditions (strictly inducible), while some are present in cells under normal growth conditions and are not heat-inducible (constitutive or cognate) [PMID: 2143562, PMID: 2841196]. Hsp70 proteins can be found in different cellular compartments(nuclear, cytosolic, mitochondrial, endoplasmic reticulum, for example).

This entry represents three conserved sites of the heat shock 70 protein family.
