WebSep 18, 2002 · CHIP expression shortens the half-life of both nascent and mature ErbB2 protein. In vitro ubiquitination assay shows that CHIP serves as a ubiquitin ligase for ErbB2, and both exogenously expressed and endogenous CHIP coprecipitate with the kinase. Furthermore, CHIP association with ErbB2 requires a chaperone intermediate and is … WebWe investigated the role of the E3 ligase carboxyl terminus of Hsc70-interacting protein (CHIP) in the regulation of MLK3 protein levels. We show that CHIP interacts with MLK3 and, together with the E2 ubiquitin-conjugating enzyme UbcH5 (UbcH5a, -b, -c, or -d), ubiquitinates MLK3 in vitro.

WebCHIP acts as an E3 ligase for Src and PKCζ during TLR signaling. CHIP-mediated enhancement of TLR signaling is inhibited by IFNAR deficiency or expression of ubiquitination resistant mutant forms of Src or PKCζ. These findings suggest that CHIP facilitates the formation of a TLR signaling complex by recruiting, ubiquitinating, and … WebThe ligase chain reaction (LCR) is an amplification process that differs from PCR in that it involves a thermostable ligase to join two probes or other molecules together which can …
WebDec 1, 2009 · The Cullin family of RING E3 ubiquitin ligases are modular enzymes that act as a scaffolding to bring a specific substrate within close proximity to the E2 ubiquitin conjugating enzyme, thereby facilitating ubiquitination and subsequent proteasomal degradation (8, 9).There are seven known human Cullin proteins, Cul1, 2, 3, 4a, 4b, 5, … WebIt 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.
