Agonist Comments
FZDs are receptors for WNT proteins. Until now FZD6 has been proven to bind to WNT 3A, 4, 5A, 5B, and 7A. For more detail information see [4].

Transducer Effector/Response
Gi/Go family
Gq/G11 family
G protein independent mechanism
Comments:  FZD6-mediated Gαo activation in an E. coli reconstitution system has been shown [9]. FZD6 is precoupled to Gαi and Gαq [10]. Transduction is, β-catenin-dependent and β-catenin-independent WNT, dependent on DVL [1].
