Is predicted to encode a protein with the following domains: SMARCC, SWIRM-associated domain; SANT/Myb domain; SWI/SNF complex subunit SMARCC1; Myb-like DNA-binding domain; SWIRM-associated domain at the C-terminal; SWIRM-associated region 1; Winged helix-like DNA-binding domain superfamily; SWIRM domain; Homeobox-like domain superfamily; and SMARCC, C-terminal. Is an ortholog of C. elegans swsn-1. In C. elegans, swsn-1 is involved in several processes, including determination of adult lifespan; negative regulation of vulval development; and positive regulation of growth rate.
