This gene encodes a member of the beta-transducin protein family. Most proteins of the beta-transducin family are involved in regulatory functions. This protein is possibly involved in some intracellular signaling pathway. This gene is deleted in Williams-Beuren syndrome, a developmental disorder caused by deletion of multiple genes at 7q11.23.Synonyms: Transducin beta-like protein 2, WBSCR13, WS beta-transducin repeats protein, Williams-Beuren syndrome chromosomal region 13 protein
