Is predicted to encode a protein with the following domains: Protein lin-7; PDZ superfamily; L27 domain; PDZ domain; L27 domain, C-terminal; and L27 domain superfamily. Is an ortholog of C. elegans lin-7. In C. elegans, lin-7 is involved in several processes, including egg-laying behavior; positive regulation of vulval development; and protein localization to basolateral plasma membrane.
