Data indicate a coordinated regulation of Arabidopsis proteins SHW1, COP1, and HY5 in seedling development.
The COP1 role in CONSTANS protein degradation during photoperiodic flowering
CSU2 interacts with COP1 via the coiled-coil domain association. CSU2 negatively regulates COP1 E3 ubiquitin ligase (show MUL1 Antibodies) activity. [COP1]
propose that light perceived by phytochromes causes a switch in the ubiquitination activity of COP1/SPA2 from ubiquitinating downstream substrates to ubiquitinating SPA2, which subsequently causes a repression of COP1/SPA2 function
CUL4(COP1-SPA) E3 ubiquitin ligase is necessary for the light-induced degradation of PIF1 in Arabidopsis.
genetic analyses with transgenes expressing a genomic pmARI12:ARI12-GFP construct confirm the epistatic interaction between COP1 and ARI12 in growth responses to high fluence rate UV-B.
Interaction of phyB with SPA1 promotes COP1-SPA1 dissociation and photomorphogenic development.
AN3 may act with other proteins that bind to COP1 promoter to promote anthocyanin accumulation and inhibit light-induced root elongation.
Two distinct domains of the UVR8 photoreceptor interact with COP1 to initiate UV-B signaling in Arabidopsis
The Transcriptional Regulator BBX19 Promotes Hypocotyl Growth by Facilitating COP1-Mediated EARLY FLOWERING3 Degradation in Arabidopsis
Study shows that post-translational regulation of the transcription factors ETV1 (show ETV1 Antibodies), ETV4 (show ETV4 Antibodies), and ETV5 (show ETV5 Antibodies) by the ubiquitin ligase (show RNF123 Antibodies) COP1 (also called RFWD2) in beta cells is critical for insulin (show INS Antibodies) secretion. Mice lacking COP1 in beta cells developed diabetes due to insulin (show INS Antibodies) granule docking defects that were fully rescued by genetic deletion of Etv1 (show ETV1 Antibodies), Etv4 (show ETV4 Antibodies), and Etv5 (show ETV5 Antibodies).
These results indicate that COP1 and Trib1 (show TRIB1 Antibodies) act as an oncoprotein complex functioning upstream of C/EBPalpha (show CEBPA Antibodies), and its ligase activity is crucial for leukemogenesis.
COP1 physically interacted with PTP1B (show PTPN1 Antibodies) and suppressed PTP1B (show PTPN1 Antibodies) phosphatase activity as well as the association of PTP1B (show PTPN1 Antibodies) with IRbeta.
Modulation of fatty acid synthase (show FASN Antibodies) degradation by concerted action of p38 MAP kinase (show MAPK14 Antibodies), E3 ligase COP1, and SH2 (show MYO15 Antibodies)-tyrosine phosphatase Shp2 (show PTPN11 Antibodies).
the ubiquitin ligase (show RNF123 Antibodies) COP1 (also known as RFWD2) is a tumour suppressor that negatively regulates ETV1 (show ETV1 Antibodies), ETV4 (show ETV4 Antibodies) and ETV5 (show ETV5 Antibodies); ETV1 (show ETV1 Antibodies), which is mutated in prostate cancer more often, was degraded after being ubiquitinated by COP1
Cop1 is a tumor suppressor that functions, at least in part, by antagonizing c-Jun (show JUN Antibodies) oncogenic activity.
Rfwd2 is associated with acute lung injury
description of a pathway in which Tribbles 3 (TRB3 (show TRIB3 Antibodies)) stimulates lipolysis by triggering the degradation of acetyl-coenzyme A carboxylase (ACC (show ACACA Antibodies)) in adipose tissue; TRB3 (show TRIB3 Antibodies) promoted ACC (show ACACA Antibodies) ubiquitination through an association with the E3 ubiquitin ligase (show MUL1 Antibodies) COP1
Disruption of the COP1-mediated proteolysis by ionizing radiation leads to MTA1 (show MTA1 Antibodies) stabilization.
the reduced expression of COP1 (show CARD16 Antibodies) and the upregulated expression of ETV1 (show ETV1 Antibodies) in RCC (show XRCC1 Antibodies) tissue samples, which was associated with a high tumor-node-metastasis stage of RCC (show XRCC1 Antibodies). Furthermore, the overexpression of COP1 (show CARD16 Antibodies) in the RCC (show XRCC1 Antibodies) ACHN (show LARP6 Antibodies) cells inhibited the migration and invasion of ACHN (show LARP6 Antibodies) cells, and downregulated ETV1 (show ETV1 Antibodies) and MMP7 (show MMP7 Antibodies) expression levels.
COP1 (show CARD16 Antibodies) expression was an independent predictor of overall survival.
the present study revealed that COP1 (show CARD16 Antibodies) plays an important role in CLL cell proliferation and tumorigenicity, and may be a useful indicator of the chronic lymphocytic leukemia processes.
COP1 (show CARD16 Antibodies) directly interacts with p27 (show PAK2 Antibodies) through a VP motif on p27 (show PAK2 Antibodies) and functions as an E3 ligase of p27 (show PAK2 Antibodies) to accelerate the ubiquitin-mediated degradation of p27 (show PAK2 Antibodies). COP1 (show CARD16 Antibodies)-p27 (show PAK2 Antibodies) axis deregulation is involved in tumorigenesis.
COP1 (show CARD16 Antibodies) overexpression leads to the cytoplasmic distribution of p27 (show PAK2 Antibodies), thereby accelerating p27 (show PAK2 Antibodies) degradation.
COP1 (show CARD16 Antibodies) negatively regulates ETV1 (show ETV1 Antibodies) in patients with triple-negative breast cancer.
TRIB2 (show TRIB2 Antibodies) associated-ubiquitin E3 ligases beta-transducin repeat-containing E3 ubiquitin protein ligase (beta-TrCP (show BTRC Antibodies)), COP1 (show CARD16 Antibodies) and Smad ubiquitination regulatory factor 1 (Smurf1 (show SMURF1 Antibodies)) reduced TCF4 (show TCF4 Antibodies)/beta-Catenin (show CTNNB1 Antibodies) expression, and these effects could be enhanced by TRIB2 (show TRIB2 Antibodies).
Phosphorylation of the ETS1 (show ETS1 Antibodies) and ETS2 (show ETS2 Antibodies) transcriptional oncoproteins at specific serine or threonine residues creates binding sites for the COP1 (show CARD16 Antibodies) tumor suppressor protein (show TP53 Antibodies).
while the role of COP1 (show CARD16 Antibodies) in malignancies is controversial, our current data support that COP1 (show CARD16 Antibodies) acts as a tumor suppressor in gastric cancer.
co-expressing COP1 (show CARD16 Antibodies) and active GSK3beta (show GSK3b Antibodies) blocked in vitro cell growth/migration and in vivo metastasis of invasive breast cancer cells.
E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of target proteins. E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin- conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Involved in JUN ubiquitination and degradation. Directly involved in p53 (TP53) ubiquitination and degradation, thereby abolishing p53-dependent transcription and apoptosis. Ubiquitinates p53 independently of MDM2 or RCHY1. Probably mediates E3 ubiquitin ligase activity by functioning as the essential RING domain subunit of larger E3 complexes. In contrast, it does not constitute the catalytic RING subunit in the DCX DET1-COP1 complex that negatively regulates JUN, the ubiquitin ligase activity being mediated by RBX1 (By similarity).
