WebApr 5, 2024 · From an array of candidates, Kim and colleagues focused on three proteins that functionally converge on the regulation of the ubiquitin ligase carboxy-terminus of Hsc70-interacting protein (CHIP). They showed that CHIP-mediated ubiquitination of tau, which drives chaperone-dependent tau degradation via the proteasome, WebFeb 1, 2001 · Subsequent studies found that CHIP co-localizes and interacts with proteasome subunits [70] [71][72], reinforcing CHIP's role in chaperone-mediated …
The E3 Ligase CHIP: Insights into Its Structure and Regulation
WebFeb 7, 2014 · The carboxy-terminus of Hsc70 interacting protein (CHIP) is a cochaperone E3 ligase containing three tandem repeats of tetratricopeptide (TPR) motifs and a C-terminal U-box domain separated by a charged coiled-coil region. CHIP is known to function as a central quality control E3 ligase and regulates several proteins involved in a myriad of … WebJan 1, 2016 · These results suggest that hPXR is regulated through its phosphorylation at threonine-408 by PKC, CHIP/chaperone–dependent stability check, and autophagic degradation pathway. The human pregnane X receptor (hPXR) is a xenobiotic-sensing nuclear receptor that transcriptionally regulates drug metabolism–related genes. The aim … great how thou art
The co-chaperon CHIP regulates protein triage decisions mediated …
WebWe also identified carboxyl terminus of heat shock cognate 70-interacting protein (CHIP), an important chaperone-dependent E3 ubiquitin ligase that couples protein folding/refolding to protein degradation, as an interacting protein of PRMT5 via mass spectrometry. Their interaction was further verified by co-immuoprecipitation, GST pull-down ... WebDec 1, 2005 · To examine whether the ubiquitin ligase activity and chaperone interaction domain are required for CHIP-induced ERα degradation, two mutant CHIP constructs were used: 1) CHIP(K30A), a TPR domain mutant unable to interact with Hsp/Hsc70 or Hsp90; and 2) CHIP(H260Q), a U-box domain mutant unable to catalyze protein ubiquitin … WebDec 8, 2000 · We estimate that Hsc70, Hdj-2 and CHIP represent 1.3, 0.23 and 0.02% of total protein in HEK293 cells. Thus, the levels of Hdj-2 are about 10 times greater than … floating handheld gps
