Predicted to enable several functions, including chromatin binding activity; nuclear receptor binding activity; and nuclear receptor coactivator activity. Acts upstream of or within several processes, including heart morphogenesis; neural retina development; and positive regulation of transcription, DNA-templated. Located in nucleus. Part of SWI/SNF complex; nBAF complex; and npBAF complex. Is expressed in several structures, including cardiogenic plate; central nervous system; ear; genitourinary system; and skin. Orthologous to human SMARCD3 (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily d, member 3). [provided by Alliance of Genome Resources, Apr 2022]
