Mybbp1a Gene Summary [Rat]
Enables sequence-specific DNA binding activity. Predicted to be involved in several processes, including cellular response to glucose starvation; positive regulation of anoikis; and regulation of gene expression. Predicted to act upstream of with a negative effect on regulation of G1 to G0 transition. Predicted to act upstream of or within respiratory electron transport chain. Predicted to be located in cytoplasm and nucleus. Predicted to be part of B-WICH complex and NLS-dependent protein nuclear import complex. Predicted to be active in nucleolus. Orthologous to human MYBBP1A (MYB binding protein 1a). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Mybbp1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
