Protein Name:
Myb-binding protein 1A
|
UniprotKB/SwissProt ID: Q9BQG0 (Q9BQG0)
Gene Name:
MYBBP1A
Organism: Homo sapiens (Human)
Function: May activate or repress transcription via interactions with sequence specific DNA-binding proteins (By similarity). Repression may be mediated at least in part by histone deacetylase activity (HDAC activity) (By similarity). Acts as a corepressor and in concert with CRY1, represses the transcription of the core circadian clock component PER2 (By similarity). Preferentially binds to dimethylated histone H3 'Lys-9' (H3K9me2) on the PER2 promoter (By similarity). Has a role in rRNA biogenesis together with PWP1 (PubMed:29065309)
