一般描述

Monoclonal Anti-STUB1/CHIP (mouse IgG2b isotype) is derived from the hybridoma ST21.55 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic peptide corresponding to amino acids 30-45 of human STUB1/CHIP. STUB1/CHIP (carboxyl terminus of Hsc70-interacting protein) consists of three functional domains: a tetratricopeptide repeat (TRP) at the amino terminus, a U- box domain at the C-terminus, and a highly charged region separating the two.
STUB1 (STIP1 homology and U-box containing protein 1) or CHIP (carboxyl terminus of Hsc70- interacting protein) is an E3 ubiquitin ligase, (2) that is located on human chromosome 16p13.3.

免疫原

synthetic peptide corresponding to amino acids 30-45 of human STUB1/CHIP.

应用

Anti-STUB1/CHIP antibody, mouse monoclonal has been used in immunoblotting and enzyme-linked immunosorbent assay (ELISA).

生化/生理作用

In lens epithelial cells, knocking down CHIP (carboxyl terminus of Hsc70- interacting protein) decreased the reaction of heat shock and potential of protein quality control. It plays a major role in neurodegeneration and also controls autophagic flux. It can deactivate NF-κB signaling and damage the capability of migration and invasion in gastric cancer cells.
STUB1/CHIP (carboxyl terminus of Hsc70-interacting protein) is such a cofactor, which interacts, among others, with Hsc70 and acts as a U-box-dependent E3 ubiquitin ligase. STUB1/CHIP can also act as a direct chaperone of p53, both under physiological and stress conditions.
