Is predicted to encode a protein with the following domains: Rad60/SUMO-like domain; Ubiquitin-2 like Rad60 SUMO-like; Ubiquitin-like domain superfamily; and Ubiquitin-like domain. Is an ortholog of C. elegans
smo-1. In C. elegans,
smo-1 is involved in several processes, including chromosome organization; multicellular organismal locomotion; and muscle cell cellular homeostasis.
