Is predicted to encode a protein with the following domains: G-protein beta WD-40 repeat; WD40/YVTN repeat-like-containing domain superfamily; WD40 repeat; WD domain, G-beta repeat; and WD40-repeat-containing domain superfamily. Is an ortholog of C. elegans rack-1. In C. elegans, rack-1 is involved in several processes, including antifungal innate immune response; cytoskeleton-dependent cytokinesis; and motor neuron axon guidance.
