Background

Gastrokine-1 (GKN1; also CA11 and AMP-18) is an 18-20 kDa member of the Gastrokine protein family. It has limited expression, being restricted to mucous secreting pyloric antrum epithelial cells. Gastrokine-1 appears to promote epithelial cell proliferation and migration, and induce the formation of tight junctions between epithelial cells. By contrast, gastrokine-1 induces Fas expression in tumor cells, resulting in apoptosis. Mature mouse gastrokine-1 is 166 amino acids (aa) in length (aa 36-201). Based on the SwissProt sequence, it possesses one BRICHOS domain (aa 71-165) that contains a mitogenic sequence (aa 113-131). There is one potential alternative start site at Met18. Over aa 38-201, mouse gastrokine-1 shares 65% and 92% aa sequence identity with human and rat gastrokine-1, respectively.

Limitations
