DESCRIPTION

Also known as WNT3A_HUMAN, WNT3A. Ligand for members of the frizzled family of seven transmembrane receptors (Probable). Functions in the canonical Wnt signaling pathway that results in activation of transcription factors of the TCF/LEF family (PubMed:20093360, PubMed:21244856, PubMed:24841207, PubMed:26902720). Required for normal embryonic mesoderm development and formation of caudal somites. Required for normal morphogenesis of the developing neural tube (By similarity). Mediates self-renewal of the stem cells at the bottom on intestinal crypts (in vitro) (PubMed:26902720). Forms a soluble 1:1 complex with AFM; this prevents oligomerization and is required for prolonged biological activity (PubMed:26902720). The complex with AFM may represent the physiological form in body fluids (PubMed:26902720). Homooligomer; disulfide-linked, leading to inactivation (By similarity). Interacts with PORCN (PubMed:20826466). Interacts with APCDD1 and WLS (PubMed:16678095, PubMed:20393562). Component of the Wnt-Fzd-LRP5-LRP6 signaling complex that contains a WNT protein, a FZD protein and LRP5 or LRP6. Interacts directly in the complex with LRP6 (PubMed:20093360). Interacts with glypican GPC3 (PubMed:16227623). Interacts with PKD1 (via extracellular domain) (PubMed:27214281).
