Hdac3 | Histone deacetylase 3; Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4), and some other non-histone substrates. Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Participates in the BCL6 transcriptional repressor activity by deacetylating the H3 'Lys-27' (H3K27) on enhancer elements, antagonizing EP300 acetyltransferase activi [...] (428 aa) | ||||
Trib1 | Tribbles homolog 1; Adapter protein involved in protein degradation by interacting with COP1 ubiquitin ligase. Promotes CEBPA degradation and inhibits its function. Controls macrophage, eosinophil and neutrophil differentiation via the COP1-binding domain. Regulates myeloid cell differentiation by altering the expression of CEBPA in a COP1-dependent manner. Interacts with MAPK kinases and regulates activation of MAP kinases, but has no kinase activity (By similarity). Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. Tribbles subfamily. (372 aa) |
