Is predicted to encode a protein with the following domains: WD domain, G-beta repeat; CTLH, C-terminal LisH motif; G-protein beta WD-40 repeat; WD40 repeat; WD40/YVTN repeat-like-containing domain superfamily; LisH-like dimerisation domain; LIS1 homology motif; and WD40-repeat-containing domain superfamily. Is an ortholog of C. elegans smu-1. In C. elegans, smu-1 is involved in several processes, including mechanosensory behavior; nematode larval development; and regulation of alternative mRNA splicing, via spliceosome.
