Anti-HSP60: Mouse HSP60 Antibody |
 |
BACKGROUND Human HSP60, the product of the HSPD1 gene, is a Group I mitochondrial chaperonin, phylogenetically related to bacterial GroEL. HSP60 has long been known as an important chaperonin and as having key folding functions within the mitochondria. It is involved in mitochondrial protein import and macromolecular assembly and facilitates the correct folding of imported proteins. It may also prevent misfolding and promote the refolding and proper assembly of unfolded polypeptides generated in the mitochondrial matrix under stress conditions.1
Recently, the presence of HSP60 outside the mitochondria and outside the cell, e.g. in circulating blood, has been reported.2 This extra-mitochondrial HSP60 in the heart has key anti-apoptotic functions. Extra-mitochondrial HSP60 complexes with both bax and bak, but not with bcl-2. Reduction in HSP60 is sufficient to precipitate apoptosis. However, HSP60 may participate in triggering apoptosis in other cells. In addition, HSP60 has been found on the cell-membrane's outer surface in both normal and tumor cells. It has been implicated in transmembrane transport and signaling, activation and maturation of dendritic cells with generation of antitumor T-cell responses. Microbial HSP60 constitutes a major antigen recognized by the immune system during bacterial infections. Owing to the strong homology between microbial and human HSP60 an immune reaction against infectious microbes may lead to a cross-reactive autoimmune response against the native human HSP60.3
