Recombinant Human STIP1 Homology And U-box Containing Protein 1

Cat. No.: STUB1-336H
Product Overview: Recombinant human CHIP protein was expressed in E.coli and purified by using conventional chromatography techniques (303 aa, 34.8 kDa).
Description: CHIP, also known as STUB1, is a cytoplasmic protein whose amino acid sequence is highly conserved across species. CHIP interacts with the molecular chaperones Hsc70-Hsp70 and Hsp90 through its TPR domain, whereas its U-box domain contains its E3 ubiquitin ligase activity. Its interaction with these molecular chaperones results in client substrate ubiquitylation and degradation by the proteasome. Thus, CHIP acts to tilt the folding-refolding machinery toward the degradative pathway, and it serves as a link between the two.
Source: E.coli.
Formulation: Liquid. In 20 mM Tris-HCl buffer (pH 7.5) containing 5 mM DTT, 10% glycerol.
Molecular Weight: 34.8 kDa (303 aa).
Purity: > 90% by SDS – PAGE.
