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 (显示 NBR1 ELISA试剂盒) 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 (显示 Psmd4 ELISA试剂盒) 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.
Consistent with reduced transcription factor EB (TFEB) activity, accumulation of phosphorylated TFEB in STUB1-deficient cells resulted in reduced autophagy and reduced mitochondrial biogenesis. These studies reveal that the ubiquitin-proteasome pathway participates in regulating autophagy and lysosomal functions by regulating the activity of TFEB.
ACR (显示 ACR ELISA试剂盒) 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 (显示 ACR ELISA试剂盒), and CRL4(CRBN (显示 CRBN ELISA试剂盒)), which is formed by Cul4a (显示 CUL4A ELISA试剂盒)/b, Ddb1, and Crbn (显示 CRBN ELISA试剂盒), and interacts with the COOH terminus of the ACR (显示 ACR ELISA试剂盒) via Crbn (显示 CRBN ELISA试剂盒).
The chaperone protein Hsp70 (显示 HSP70 ELISA试剂盒) was found to be important for CHIP and NUCB1 (显示 NUCB1 ELISA试剂盒) interaction as well as CHIP-mediated NUCB1 (显示 NUCB1 ELISA试剂盒) down-regulation.
CHIP is a negative regulator of RIPK1 (显示 RIPK1 ELISA试剂盒) and RIPK3 (显示 RIPK3 ELISA试剂盒), thus inhibiting necroptosis.
our study demonstrated that over-expressing miR (显示 MLXIP ELISA试剂盒)-21 in UCBMSCs could improve neovascularization in Critical limb ischemia (CLI (显示 CLU ELISA试剂盒)) through enhancing HIF-1alpha (显示 HIF1A ELISA试剂盒) activity by targeting CHIP, which may hold great therapeutic promise in treating CLI (显示 CLU ELISA试剂盒)

CHIP targets Osx (显示 SP7 ELISA试剂盒) for ubiquitination and degradation in osteoblasts after chronic exposure to TNF-alpha (显示 TNF ELISA试剂盒).
CHIP/TRAF3 (显示 TRAF3 ELISA试剂盒)/NIK (显示 MAP4K4 ELISA试剂盒) interactions recruit NIK (显示 MAP4K4 ELISA试剂盒) to E3 ligase complexes for ubiquitination and degradation, thus maintaining NIK (显示 MAP4K4 ELISA试剂盒) at low levels
Cbl-b, together with Stub1, ubiquitinate Foxp3 (显示 FOXP3 ELISA试剂盒), and regulate tTreg development.
CHIP regulates the levels of FMR1 (显示 FMR1 ELISA试剂盒) as an E3 ubiquitin ligase in phosphorylation-dependent manner, suggesting that CHIP regulates FMR1 (显示 FMR1 ELISA试剂盒)-mediated translational repression by regulating the levels of FMR1 (显示 FMR1 ELISA试剂盒).
these findings indicate that the stability of the DDIAS protein is regulated by CHIP/HSP70 (显示 HSP70 ELISA试剂盒)-mediated proteasomal degradation and that CHIP overexpression stimulates the apoptosis of lung cancer cells in response to DNA-damaging agents
Study reveals a mechanism that the Warburg effect is regulated by CHIP through its function as an E3 ligase, which mediates the degradation of PKM2 during tumor progression.
The E3 ubiquitin ligase STUB1 is a negative regulator of both RUNX1 (显示 RUNX1 ELISA试剂盒) and RUNX1 (显示 RUNX1 ELISA试剂盒)-RUNX1T1 (显示 RUNX1T1 ELISA试剂盒). Activation of STUB1 could be a promising therapeutic strategy for RUNX1 (显示 RUNX1 ELISA试剂盒)-RUNX1T1 (显示 RUNX1T1 ELISA试剂盒) leukemia.
Data show that carboxyl-terminus of Hsp70-interacting protein (CHIP) promotes polyubiquitination of transglutaminase 2 (TG2 (显示 TGM2 ELISA试剂盒)) and its subsequent proteasomal degradation.
we report the identification of an unconventional p14ARF degradation pathway induced by the chaperone HSP90 in association with the E3 ubiquitin ligase C-terminus of HSP70-interacting protein (CHIP).
C terminus of Hsc70-interacting protein (显示 ST13 ELISA试剂盒) (CHIP) selectively interacted with epidermal growth factor receptor (EGFR (显示 EGFR ELISA试剂盒)) mutants and simultaneously induced their ubiquitination and proteasomal degradation.
Study reveals an important function of CHIP-mediated proteolysis in insulin (显示 INS ELISA试剂盒) and IGF1 (显示 IGF1 ELISA试剂盒) signaling; upon proteotoxic stress conditions and during aging, CHIP is recruited toward disposal of misfolded proteins, reducing its capacity to degrade the INSR (显示 INSR ELISA试剂盒); identify a degradation pathway that controls the level of active DAF-2 (显示 INSR ELISA试剂盒)/INSR (显示 INSR ELISA试剂盒) in C. elegans, Drosophila and human cells.
Overexpression of CHIP decreased intracellular protein (显示 CKAP2 ELISA试剂盒) levels of both G2385R mutant and wild-type LRRK2 (显示 LRRK2 ELISA试剂盒), while short interfering RNA CHIP knockdown had the opposite effect
CHIP directly regulates the stability of CD166 protein through the ubiquitin proteasome system.
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
