Mouse Wnt-2b (also known as Wnt-13) is a member of the large and highly conserved Wnt family of signaling molecules that have roles in pattern formation, cell fate decision, axon guidance, and tumor formation (1). Mouse Wnt-2b is 389 amino acids (aa) in length and includes a signal peptide (2). Mature mouse Wnt-2b has a predicted molecular mass of 38 kDa and shares 96% aa sequence identity with the human protein. Wnt-2b initiates B-catenin-mediated canonical signaling and is implicated in the development of the lung, kidney, liver, and eye, as well as being present in ovarian surface epithelial cells (3-8). Pathological expression of Wnt-2b in tumors is correlated with increased cell proliferation and decreased survival (9).
