Secondary Information

Presence in other biological fluids/tissue/cells cytosol, mitochondria, endoplasmic reticulum, and nucleus
Protein Function bind ATP; molecular chaperone normal unstressed cells; role in modifying antigen presentation; glial-axon transfer proteins; interact directly with fatty acids - interaction may be part of their mode of binding to cell membranes; resist noxious stimuli both in vitro and in vivo; protection of human monocytes from hydrogen peroxideinduced toxicity; guinea pig gastric mucosal cells from ethanol damage
Biochemical Properties b-sheet structures are the most hydrophobic parts of HSC-70 and thus are likely to be involved in the binding of hydrophobic peptides; changes in resting pHi neither affect the baseline levels of HSP-70 nor alter the ability of heat shock to induce HSP-70 as found in human A-431 cells;
Significance in milk heat stress proteins in mamary gland
PTMs O glycosylation was found in HSP6, a member of HSP 70 family; presence of N-acetyl glucosamine
