Description : |
Wnt-3 is one of 19 vertebrate members of the Wingless-type MMTV integration site (Wnt) family of highly conserved cysteine-rich secreted glycoproteins that are important for normal developmental pr centigradeesses. Mouse Wnt-3 shares 99% and 100% amino acid (aa) identity with human and rat Wnt-3, respectively. It also shares 87% aa identity with mouse Wnt3a. Wnts bind to the cell surface Frizzled family receptors in conjunction with low-density lipoprotein receptor-related protein family receptors (LRP5 or 6) resulting in the stabilization of intracellular beta -catenin levels. As intracellular beta -catenin levels rise, it binds to TCF/LEF transcription factors, leading to expression of Wnt target genes. Wnts are known to bind to sFRPs, a family of secreted molecules that contain an N-terminal cysteine-rich domain (CRD) highly similar to the CRDs of the Frizzled family receptors. More than one molecule of sFRP is suggested to participate in the interaction with each Wnt molecule. Both sFRP-1 and sFRP-2 can inhibit Wnt-3a activity while sFRP-3 cannot. |
