Enables chromatin binding activity. Involved in spermatid development. Predicted to be located in chromatin; intermediate filament cytoskeleton; and nucleoplasm. Predicted to be part of SWI/SNF complex; nBAF complex; and npBAF complex. Predicted to be active in nucleus. Orthologous to human SMARCA2 (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 2). [provided by Alliance of Genome Resources, Apr 2022]
