A secreted glycoprotein patterning switch with different roles in different tissues and signaling has generally been divided into the canonical and non-canonical pathways. The name was derived from two drosophila phenotypes wingless and int and the gene was first defined as a protooncogene, int1. Humans have 19 identified members, with the major subgroup of Wnts (WNT1, WNT3A, WNT8) signaling through activation of beta-catenin dependent transcription from at least 4 WNT genes encoding secreted glycoproteins. At least one wnt receptor called frizzled (FZD). Wnt7a is secreted protein and binds to extracellular matrix. The mechanism of Wnt distribution (free diffusion, restricted diffusion and active transport) and all its possible cell receptors are still being determined. In the gastrointestinal system, Wnt maintains the pool of undifferentiated intestinal progenitor cells and control maturation and correct positioning of the Paneth cell (a differentiated intestinal cell type).
