Is predicted to encode a protein with the following domains: G-protein beta WD-40 repeat; LIS1 homology motif; WD40-repeat-containing domain superfamily; CTLH, C-terminal LisH motif; WD40/YVTN repeat-like-containing domain superfamily; WD domain, G-beta repeat; WD40 repeat; and LisH-like dimerisation domain. 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.
