| TRIB2 | Tribbles homolog 2; Interacts with MAPK kinases and regulates activation of MAP kinases. Does not display kinase activity (By similarity). Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. Tribbles subfamily. (343 aa) | ||||
| TRIB1 | Tribbles homolog 1; Adapter protein involved in protein degradation by interacting with COP1 ubiquitin ligase. The COP1- binding motif is masked by autoinhibitory interactions with the protein kinase domain. Serves to alter COP1 substrate specificity by directing the activity of COP1 toward CEBPA. Binds selectively the recognition sequence of CEBPA. 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 wit [...] (372 aa) | ||||
| TRIB3 | Tribbles homolog 3; Disrupts insulin signaling by binding directly to Akt kinases and blocking their activation. May bind directly to and mask the 'Thr- 308' phosphorylation site in AKT1. Binds to ATF4 and inhibits its transcriptional activation activity. Interacts with the NF-kappa-B transactivator p65 RELA and inhibits its phosphorylation and thus its transcriptional activation activity. Interacts with MAPK kinases and regulates activation of MAP kinases. May play a role in programmed neuronal cell death but does not appear to affect non-neuronal cells. Does not display kinase activi [...] (385 aa) | ||||
| STK40 | Serine/threonine-protein kinase 40; May be a negative regulator of NF-kappa-B and p53-mediated gene transcription. (440 aa) | ||||
