Is predicted to encode a protein with the following domains: WD40/YVTN repeat-like-containing domain superfamily; Histone-binding protein RBBP4 or subunit C of CAF1 complex; and Histone-binding protein RBBP4, N-terminal. Is an ortholog of C. elegans lin-53. In C. elegans, lin-53 is involved in several processes, including cell fate specification; embryonic digestive tract morphogenesis; and nematode male tail tip morphogenesis.
