CHIP/STUB1 Proteins and Enzymes

STIP1 Homology and U-box Containing Protein 1 (STUB1), also known as Carboxyl Terminus of Hsp70-interacting Protein (CHIP), is a cytoplasmic protein that functions as a U-box Ubiquitin ligase (E3). It is highly expressed in striated muscle and brain and has been observed at lower levels in other organs including the pancreas, lung, liver, and kidney. STUB1/CHIP is 303 amino acids (aa) in length with a predicted molecular weight of 34.8 kDa. Human STUB1/CHIP shares 97% aa sequence identity with ...
