Enables RNA binding activity. Acts upstream of or within neurogenesis. Part of SWI/SNF complex; nBAF complex; and npBAF complex. Is expressed in several structures, including alimentary system; branchial arch; central nervous system; genitourinary system; and sensory organ. Human ortholog(s) of this gene implicated in familial meningioma. Orthologous to human SMARCE1 (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily e, member 1).
