Predicted to enable lysine-acetylated histone binding activity; nucleosomal histone binding activity; and protein serine/threonine kinase activity. Involved in regulation of gene expression. Acts upstream of or within neural tube closure. Located in cytoplasm and nucleus. Is expressed in several structures, including central nervous system; future brain; jaw; retina; and urinary system. Human ortholog(s) of this gene implicated in B-cell lymphoma; B-lymphoblastic leukemia/lymphoma; juvenile myoclonic epilepsy; and photosensitivity disease. Orthologous to human BRD2 (bromodomain containing 2). [provided by Alliance of Genome Resources, Apr 2022]
