Through selective degradation of Clp subunits, AtCHIP could positively regulate homeostasis of Clp proteolytic subunits and maximize the production of functional chloroplasts. Similar results were obtained from transgenic tobacco plants.
we propose that CHIP and NBR1 (show NBR1 ELISA Kits) mediate two distinct but complementary anti-proteotoxic pathways and protein's propensity to aggregate under stress conditions is one of the critical factors for pathway selection of protein degradation
Hsc70-4 and CHIP were highly induced in ppi2 mutant plants, where they mediated the degradation of chloroplast-targeted precursors through the ubiquitin-26S proteasome (show Psmd4 ELISA Kits) system.
AtCHIP, an E3 ubiquitin liagase, functions upstream of protein phosphatase 2A in stress-responsive signal transduction pathways under conditions of low temperature or in the dark. [AtCHIP]
The interaction of CHIP with FtsH1 in vitro, in normal and in CHIP-over-expressing plants is reported.
ACR (show ACR ELISA Kits) interacts with proteins that regulate the ubiquitin-proteasome system, predominantly with the E3 ubiquitin-protein ligases Stub1, which binds the NH2 terminus of the ACR (show ACR ELISA Kits), and CRL4(CRBN (show CRBN ELISA Kits)), which is formed by Cul4a (show CUL4A ELISA Kits)/b, Ddb1 (show DDB1 ELISA Kits), and Crbn (show CRBN ELISA Kits), and interacts with the COOH terminus of the ACR (show ACR ELISA Kits) via Crbn (show CRBN ELISA Kits).
The chaperone protein Hsp70 (show HSP70 ELISA Kits) was found to be important for CHIP and NUCB1 (show NUCB1 ELISA Kits) interaction as well as CHIP-mediated NUCB1 (show NUCB1 ELISA Kits) down-regulation.
CHIP is a negative regulator of RIPK1 (show RIPK1 ELISA Kits) and RIPK3 (show RIPK3 ELISA Kits), thus inhibiting necroptosis.
our study demonstrated that over-expressing miR (show MLXIP ELISA Kits)-21 in UCBMSCs could improve neovascularization in Critical limb ischemia (CLI (show CLU ELISA Kits)) through enhancing HIF-1alpha (show HIF1A ELISA Kits) activity by targeting CHIP, which may hold great therapeutic promise in treating CLI (show CLU ELISA Kits)
PABPN1 (show PABPN1 ELISA Kits) interacts with and is stabilized by heat shock protein 90 (show HSP90 ELISA Kits).
CHIP targets Osx (show SP7 ELISA Kits) for ubiquitination and degradation in osteoblasts after chronic exposure to TNF-alpha (show TNF ELISA Kits).
CHIP/TRAF3 (show TRAF3 ELISA Kits)/NIK (show MAP4K4 ELISA Kits) interactions recruit NIK (show MAP4K4 ELISA Kits) to E3 ligase complexes for ubiquitination and degradation, thus maintaining NIK (show MAP4K4 ELISA Kits) at low levels
Cbl-b, together with Stub1, ubiquitinate Foxp3 (show FOXP3 ELISA Kits), and regulate tTreg development.
CHIP regulates the levels of FMR1 (show FMR1 ELISA Kits) as an E3 ubiquitin ligase in phosphorylation-dependent manner, suggesting that CHIP regulates FMR1 (show FMR1 ELISA Kits)-mediated translational repression by regulating the levels of FMR1 (show FMR1 ELISA Kits).
The cardiac CHIP appears to play a role in regulating autophagy during the development of cardiac hypertrophy, possibly by its role in supporting Akt (show AKT1 ELISA Kits) signalling, induced by voluntary running in vivo.
C terminus of Hsc70-interacting protein (show ST13 ELISA Kits) (CHIP) selectively interacted with epidermal growth factor receptor (EGFR (show EGFR ELISA Kits)) mutants and simultaneously induced their ubiquitination and proteasomal degradation.
Study reveals an important function of CHIP-mediated proteolysis in insulin (show INS ELISA Kits) and IGF1 (show IGF1 ELISA Kits) signaling; upon proteotoxic stress conditions and during aging, CHIP is recruited toward disposal of misfolded proteins, reducing its capacity to degrade the INSR (show INSR ELISA Kits); identify a degradation pathway that controls the level of active DAF-2 (show INSR ELISA Kits)/INSR (show INSR ELISA Kits) in C. elegans, Drosophila and human cells.
Overexpression of CHIP decreased intracellular protein (show CKAP2 ELISA Kits) levels of both G2385R mutant and wild-type LRRK2 (show LRRK2 ELISA Kits), while short interfering RNA CHIP knockdown had the opposite effect
CHIP directly regulates the stability of CD166 protein through the ubiquitin proteasome system.
Data show that BAG2 (show BAG2 ELISA Kits) Inhibits CHIP-Mediated HSP72 (show HSPA1A ELISA Kits) ubiquitination in aged cells.
Data show that transcription factor regulatory factor X 1 (RFX1 (show RFX1 ELISA Kits)) protein expression can be tightly regulated by polyubiquitination-mediated proteosomal degradation via STIP1 homology and U-box containing protein 1 (STUB1).
CHIP may serve as a promising prognostic biomarker for non-small cell lung cancer (NSCLC] patients and it may be involved in NSCLC angiogenesis through regulating VEGF (show VEGFA ELISA Kits) secretion and expression of VEGFR2 (show KDR ELISA Kits).
Cdk5 (show CDK5 ELISA Kits)-mediated phosphorylation of CHIP negatively regulates its neuroprotective function, thereby contributing to neuronal cell death progression following neurotoxic stimuli.
CHIP is a bona fide negative regulator of the RIPK1 (show RIPK1 ELISA Kits)-RIPK3 (show RIPK3 ELISA Kits) necrosome formation leading to desensitization of TNF (show TNF ELISA Kits)-mediated necroptosis
Protein-protein interactions modulate the docking-dependent E3-ubiquitin ligase activity of CHIP.
STUB1, or CHIP, is a ubiquitin ligase/cochaperone that participates in protein quality control by targeting a broad range of chaperone protein substrates for degradation (Min et al., 2008
