Gastrokine 1 in Human Stomach. Gastrokine 1 was detected in immersion fixed paraffin-embedded sections of human stomach using Mouse Anti-Human Gastrokine 1 Monoclonal Antibody (Catalog # MAB6395) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to gastric glands.

Background: Gastrokine 1

Gastrokine 1 (GKN1; also CA11 and AMP-18) is an 18 kDa member of the CA11 protein family. It has limited expression, being restricted to mucous secreting pyloric atrial epithelium. Gastrokine 1 appears to promote epithelial proliferation and migration, and induce the formation of tight junctions between epithelial cells. Mature human Gastrokine 1 is 165 amino acids (aa) in length. Based on the SwissProt sequence, it possesses one BRICHOS domain (aa 54-150) that contains a mitogenic sequence (aa 97-117). There is one potential alternative start site 14 aa upstream of the standard site that does not appear to be utilized. Over aa 21-185 (aa 35-199 of SwissProt), human Gastrokine 1 shares 65% aa identity with mouse Gastrokine 1.
