Is predicted to encode a protein with the following domains: Homeobox-like domain superfamily; Myb-like DNA-binding domain; SMARCC, C-terminal; SWIRM domain; SMARCC, SWIRM-associated domain; Winged helix-like DNA-binding domain superfamily; SANT/Myb domain; SWI/SNF complex subunit SMARCC1; SWIRM-associated domain at the C-terminal; and SWIRM-associated region 1. 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.
