In mammals there are 19 Wnt proteins. Some Wnt members are thought to be specific to the canonical or beta-catenin dependent pathway (Wnt1, Wnt3a or Wnt8) and other to activate the non-canonical pathway beta-catenin independent  (Wnt5a or Wnt11). Recent results suggest that the outcome of Wnt signaling might be related to specific receptor or other partner interactions  as well as patterns of expression. The Wnt family members are listed with aliases in parentheses, full name and links to report pages:
