FZD4 is a seven-transmembrane glycoprotein that functions as a receptor for Wnt proteins . It can activate several signaling pathways, including the canonical Wnt/β-catenin pathway, planar cell polarity pathway, and calcium flux pathway . The activation of these pathways leads to various cellular responses, such as cell proliferation, differentiation, and migration.
FZD4 is particularly important in the development of the vascular system in the retina. It acts as a receptor for both Wnt proteins and Norrin, a protein that is crucial for retinal vascularization . Mutations in the FZD4 gene have been associated with familial exudative vitreoretinopathy (FEVR), a genetic disorder that affects the development of blood vessels in the retina .
Recombinant human FZD4 is produced using recombinant DNA technology, which involves inserting the human FZD4 gene into a suitable expression system, such as a bacterial or mammalian cell line. This allows for the production of large quantities of the protein for research and therapeutic purposes .
The recombinant protein is typically purified to high levels of purity and is used in various applications, including functional assays, structural studies, and drug development . It is often used in studies to understand the mechanisms of Wnt signaling and to develop potential therapies for diseases related to this pathway.
Recombinant human FZD4 is used in a variety of research applications, including:
