| Immunohistochemistry | FGF-15 in Mouse Embryo. FGF-15 was detected in immersion fixed frozen sections of mouse embryo (E15) using Sheep Anti-Mouse FGF-15 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6755) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # ) and counterstained with hematoxylin (blue). Specific staining was localized to the processes of dorsal root ganglia neurons. View our protocol for . |

FGF-15 (Fibroblast growth factor 15) is a 25 kDa, secreted, nonglycosylated polypeptide that is a member of the FGF-15/21/23 subfamily, FGF family of growth factors. It is synthesized by ileal epithelium, colonic myofibroblasts, and select areas of the developing brain. FGF-15 acts on hepatocytes and reduces CYP7A1 levels, thus blocking bile acid production. It also promotes colonic epithelial migration, and in the embryonic brain, inhibits over-production of neuronal precursors. FGF-15 is synthesized as a 218 amino acid (aa) precursor that contains a 25 aa signal sequence and a 182 aa mature region (aa 26-218; 23 kDa predicted MW). Mature FGF-15 contains a characteristic 3-dimensional beta -trefoil structure, plus a unique Cys pattern that contributes to stability. There are two potential splice forms. One shows a 23 aa substitution for aa 120-218, while a second shows a 41 aa substitution for aa 120-218. Over aa 23-200, mouse FGF-15 shares 96% aa identity with rat FGF-15. Although mouse FGF-15 is considered the ortholog to human FGF-19, the two molecules share only 54% aa identity over aa 23-200, and are produced by different cell types (intestinal epithelium in mouse, hepatocytes in human).
