HSPA6 | heat shock 70kDa protein 6 (HSP70B’); In cooperation with other chaperones, Hsp70s stabilize preexistent proteins against aggregation and mediate the folding of newly translated polypeptides in the cytosol as well as within organelles. These chaperones participate in all these processes through their ability to recognize nonnative conformations of other proteins. They bind extended peptide segments with a net hydrophobic character exposed by polypeptides during translation and membrane translocation, or following stress-induced damage (By similarity) (643 aa) | |||
RAD9A | RAD9 homolog A (S. pombe); Component of the 9-1-1 cell-cycle checkpoint response complex that plays a major role in DNA repair.

The 9-1-1 complex stimulates DNA polymerase beta (POLB) activity by increasing its affinity for the 3’-OH end of the primer-template and stabilizes POLB to those sites where LP-BER proceeds; endonuclease FEN1 cleavage activit [...] (391 aa) | |||
HSPH1 | heat shock 105kDa/110kDa protein 1; Prevents the aggregation of denatured proteins in cells under severe stress, on which the ATP levels decrease markedly. Inhibits HSPA8/HSC70 ATPase and chaperone activities (By similarity) (858 aa) | |||
HSPA5 | heat shock 70kDa protein 5 (glucose-regulated protein, 78kDa); Probably plays a role in facilitating the assembly of multimeric protein complexes inside the ER (654 aa) | |||
GRPEL2 | GrpE-like 2, mitochondrial (E. coli); Essential component of the PAM complex, a complex required for the translocation of transit peptide-containing proteins from the inner membrane into the mitochondrial matrix in an ATP-dependent manner. Seems to control the nucleotide-dependent binding of mitochondrial HSP70 to substrate proteins. Stimulates ATPase activity of mt-HSP70. May also serve to modulate the interconversion of oligomeric (inactive) and monomeric (active) forms of mt-HSP70 (By similarity) (225 aa) | |||
ANKRD45 | ankyrin repeat domain 45 (266 aa) | |||
HSP90AA1 | heat shock protein 90kDa alpha (cytosolic), class A member 1; Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function (854 aa) | |||
RAD1 | RAD1 homolog (S. pombe); Component of the 9-1-1 cell-cycle checkpoint response complex that plays a major role in DNA repair.
