Predicted to enable methyl-CpG binding activity and nuclear receptor coactivator activity. Predicted to be involved in several processes, including negative regulation of epithelial cell proliferation involved in prostate gland development; pole plasm assembly; and secretory columnal luminar epithelial cell differentiation involved in prostate glandular acinus development. Predicted to act upstream of or within negative regulation of cell population proliferation. Predicted to be located in Golgi apparatus and nucleus. Predicted to be part of methylosome. Predicted to be active in cytosol; nucleoplasm; and pole plasm. Orthologous to human WDR77 (WD repeat domain 77). [provided by Alliance of Genome Resources, Apr 2022]
