Ligand Sp. Action Value Parameter Reference
norrin {Sp: Mouse} Peptide Ligand is endogenous in the given species Mm Full agonist 8.4 pKd 41
pKd 8.4 [41]
Agonist Comments
Due to the lack of purified and biologically active WNTs little information on the specificity and pharmacology of FZD-WNT interaction is available. Extensive and quantitative binding assays have not been performed with mammalian FZDs. Evidence for the direct activation/interaction of FZD4 with WNT-5A [4,23], WNT-3A [24], WNT-2 [16], WNT-7B [40] and the FZD4 specific ligand Norrin [41] exist.
Antagonist Comments
Amyloid-β peptide binds with high affinity to FZD4-CRD and FZD5-Crd and inhibits β-catenin dependent signalling [21]. sFRP1 interacts with WNTs and FZD4-CRD [6].

Tissue Distribution Comments
Pinpointing one of the FZD isoforms in relationship to functional assays is compromised due to the high endogenous expression of various FZD isoforms in many cellular systems.
