Target Details for WNT2B

Target: WNT2B (Wingless-Type MMTV Integration Site Family, Member 2B (WNT2B))

Alternative Name: WNT2B

Background:

Synonyms: WNT13, Protein Wnt-2b, Protein Wnt-13, WNT2B

Background: Ligand for members of the frizzled family of seven transmembrane receptors. Probable developmental protein. May be a signaling molecule which affects the development of discrete regions of tissues. Is likely to signal over only few cell diameters. May be involved in normal development or differentiation as well as in carcinogenesis.
