TRIB1 (Q96RU8) - Overview - Molecular Target Synopsis
TRIB1, Tribbles homolog 1
Also Known as TRIB1_HUMAN, TRIB1, C8FW, GIG2, TRB1
Adapter protein involved in protein degradation by interacting with COP1 ubiquitin ligase (PubMed:27041596). The COP1-binding motif is masked by autoinhibitory interactions with the protein kinase domain (PubMed:26455797). Serves to alter COP1 substrate specificity by directing the activity of COP1 toward CEBPA (PubMed:27041596). Binds selectively the recognition sequence of CEBPA (PubMed:26455797). Regulates myeloid cell differentiation by altering the expression of CEBPA in a COP1-dependent manner (By similarity). Controls macrophage, eosinophil and neutrophil differentiation via the COP1-binding domain (By similarity). Interacts with MAPK kinases and regulates activation of MAP kinases, but has no kinase activity (PubMed:15299019, PubMed:26455797). Monomer (PubMed:26455797). Interacts (via protein kinase domain) with CEBPA (PubMed:20410507, PubMed:26455797). Interacts with COP1 (PubMed:20410507, PubMed:27041596).
