Facts about Frizzled-4.
Receptor for Wnt proteins.
Most of frizzled receptors are coupled to the beta-catenin (CTNNB1) canonical signaling pathway, which leads to the regeneration of disheveled proteins, inhibition of GSK-3 kinase, nuclear accumulation of beta-catenin (CTNNB1) and activation of Wnt target genes.Plays a crucial role in retinal vascularization by acting as a receptor for Wnt proteins and norrin (NDP). In retina, it may be equally activated by Wnt protein-binding, but also by a Wnt-independent signaling via binding of norrin (NDP), boosting in both cases beta-catenin (CTNNB1) accumulation and stimulation of LEF/TCF-mediated transcriptional programs.

Almost ubiquitous. Largely expressed in adult heart, skeletal muscle, ovary, and fetal kidney. Moderate amounts in adult liver, kidney, pancreas, spleen, and fetal lung, and small amounts in placenta, adult lung, prostate, testis, colon, fetal brain and liver.
