Function
Receptor for Wnt proteins (PubMed:19855022, PubMed:20711352). Most frizzled receptors are coupled to the beta-catenin canonical signaling pathway, which leads to the activation of disheveled proteins, inhibition of gsk-3 kinase, nuclear accumulation of beta-catenin and activation of Wnt target genes. A second signaling pathway involving PKC and calcium fluxes has been seen for some family members, but it is not yet clear if it represents a distinct pathway or if it can be integrated in the canonical pathway, as PKC seems to be required for Wnt-mediated inactivation of gsk-3 kinase. Both pathways seem to involve interactions with G-proteins (Probable). Required for the migration and axon formation and guidance of different neuronal cell types including canal-associated neurons (CAN), hermaphrodite-specific neurons (HSN), anterior lateral microtubule neurons (ALM), and the right Q neuroblast (QR) and its descendants (PubMed:16109397). Directs ALM migration through frizzled protein mom-5 and Wnt ligands cwn-1, cwn-2 and egl-20 (PubMed:16109397). May act redundantly with mom-5 to direct CAN migration (PubMed:16109397). Plays a role in the organization of head ganglion cells (PubMed:16109397). Probably by acting as a receptor for Wnt ligand cwn-2, plays a role in the positioning of the nerve ring and may in addition positively regulate the neurite outgrowth of RME GABAergic motor neurons along the anterior-posterior axis of the body (PubMed:19855022, PubMed:20711352).
