Enables chromatin binding activity and transcription coactivator activity. Acts upstream of or within animal organ development; histone H3-K4 trimethylation; and positive regulation of transcription, DNA-templated. Located in nucleus. Part of transcription regulator complex. Is expressed in several structures, including alimentary system; central nervous system; early conceptus; genitourinary system; and sensory organ. Used to study dilated cardiomyopathy. Human ortholog(s) of this gene implicated in breast cancer; colon cancer; and lung cancer. Orthologous to human NCOA6 (nuclear receptor coactivator 6).
