Protein Wnt-9b (WNT9B)

Ligand for members of the frizzled family of seven transmembrane receptors (Probable). Functions in the canonical Wnt/beta-catenin signaling pathway.

Required for normal embryonic kidney growth, and also for normal development of the urogenital tract, such as uterus and a portion of the oviduct and the upper vagina in females, and epididymis and vas deferens in males. Activates a signaling cascade from the metanephric mesenchyme that induces tubulogenesis.
