Is predicted to encode a protein with the following domains: G-protein beta WD-40 repeat; Histone-binding protein RBBP4, N-terminal; WD40/YVTN repeat-like-containing domain superfamily; Histone-binding protein RBBP4 or subunit C of CAF1 complex; WD40 repeat; WD domain, G-beta repeat; and WD40-repeat-containing domain superfamily. Is an ortholog of C. elegans Y54H5A.1.
