Background
Frizzled-4, designated CD344, is a 7-transmembrane glycoprotein of the Frizzled family within the G-protein coupled receptor superfamily. Frizzled proteins function as receptors for Wnt proteins and can activate canonical Wnt/beta-catenin signaling as well as planar cell polarity and calcium flux pathways. Frizzled-4 is particularly important in angiogenic Wnt pathway signaling. Frizzled4 plays a crucial role in maintaining the integrity of the blood-brain barrier/blood-eye barrier, and regulating the expression of related proteins in the Frizzled4/Norrin pathway can regulate the switching of the blood-brain/blood-eye barrier. Frizzled-4 plays a critical role in retinal vascularization by acting as a receptor for Wnt proteins and norrin (NDP).
