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 wdr-23. In C. elegans, wdr-23 is involved in several processes, including determination of adult lifespan; negative regulation of cellular response to manganese ion; and negative regulation of transcription by RNA polymerase II.
