Overview

Product Name HspH1 (11124P-25)

Description Recombinant human HspH1 produced in E. coli is a single, non-glycosylated polypeptide containing 894 amino acids with a molecular weight of 100kDa. It is expressed with a His-tag at the N- terminus.

Target HspH1

Product Background HspH1 is a member of the mammalian Hsp105/110 family, a subgroup of the Hsp70 family. Two isoforms of HspH1, alpha and beta, have been identified. HspH1 associates with Hsp70/Hsc70 as complexes and negatively regulates the chaperone activity of Hsp70/Hsc70 in vivo and in vitro. HspH1 is highly expressed in many human tumors.

Biological Function Acts as a nucleotide-exchange factor (NEF) for chaperone proteins HSPA1A and HSPA1B, promoting the release of ADP from HSPA1A/B thereby triggering client/substrate protein release (PubMed:24318877). 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). {UniProtKB:Q60446, UniProtKB:Q61699, PubMed:24318877}.
