Recombinant Human Fibroblast Growth Factor 19

FGF19 is a member of the Fibroblast Growth Factor family of proteins. It is in the same endocrine signaling subfamily as FGF21 and FGF23 and is the human ortholog of mouse FGF15. FGF19 is a heparin-dependent ligand and binds exclusively to FGFR4. It is essential for brain and heart development, as well as the metabolism of bile acid, hepatic protein, and glycogen. FGF19 mRNA is expressed in several tissues including fetal cartilage, skin, and retina, as well as adult gall bladder and is overexpressed in a colon adenocarcinoma cell line.
