Enables sequence-specific DNA binding activity. Predicted to be involved in several processes, including intrinsic apoptotic signaling pathway by p53 class mediator; positive regulation of anoikis; and regulation of gene expression. Predicted to act upstream of or within respiratory electron transport chain. Located in nucleus. Orthologous to human MYBBP1A (MYB binding protein 1a).
