This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD)， which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes， including cell cycle progression， signal transduction， apoptosis， and gene regulation. This protein contains 5 WD repeats， and has a structural similarity with actin-binding proteins: the D. discoideum coronin and the human p57 protein， suggesting that this protein may also be an actin-binding protein that regulates cell motility. Alternative splicing of this gene generates 2 transcript variants.
