Predicted to enable acetyltransferase activator activity and histone binding activity. Involved in histone H3-K23 acetylation. Acts upstream of or within common myeloid progenitor cell proliferation; regulation of fibroblast proliferation; and tube morphogenesis. Predicted to be located in cytosol; nucleus; and plasma membrane. Predicted to be part of MOZ/MORF histone acetyltransferase complex. Is expressed in several structures, including alimentary system; central nervous system; early conceptus; genitourinary system; and sensory organ. Used to study syndromic intellectual disability. Orthologous to human BRPF1 (bromodomain and PHD finger containing 1). [provided by Alliance of Genome Resources, Apr 2022]
