• Description: HSPA4 heat shock protein family A (Hsp70) member 4 are abundant and stress-inducible 70 kDa molecular chaperone proteinsencoded by a highly conserved, multigene family. They are monomeric proteins that can be divided into two functional domains: an N-terminal ATPase domain and a substrate binding domain that contains a highly conserved EEVD motif at its C-terminus. Hsp70s are found in the cytosol, nuclei, endoplasmic reticulum, mitochondria, and chloroplasts of eukaryotes, as well as in bacteria. They function as molecular chaperones that assist in a wide range of cellular processes, including refolding of aggregated or misfolded proteins, co- and post-translational folding and assembly of nascent peptides, membrane translocation of secretory and organellar proteins, controlling activity of regulatory nuclear receptors, kinases and transcription factors, as well as acting cooperatively with the Hsp90 chaperone system in eukaryotes. The HSPA4 chaperone cycle is ATP-dependent and initiated by transient interaction of the HSPA4 substrate binding domain with hydrophobic regions within a peptide or protein.
