Description
Fibroblast growth factor-16 (FGF16) is a member of FGF9 subfamily. All FGF family members are heparin-binding growth factors with a core 120 amino acid (aa) FGF domain that allows for a common tertiary structure. FGF-16 is most similar to FGF-9, sharing 73% aa sequence homology. Human FGF-16 shares 99% and 98.6% aa sequence identity with the mouse and rat FGF-16, respectively. FGF-16 binds to and activates FGF receptor 4. The expression pattern of FGF-16 and its effect on adipocyte proliferation suggest a role for this protein on the proliferation of embryonic brown adipose tissue. FGF16 belongs to the large FGF family, which plays key role in promoting mitosis and cell survival, and also involved in embryonic development, cell growth, tissue repair, morphogenesis, tumor growth, and invasion. Meanwhile, the expression of FGF-16 in the perinatal and postnatal heart and its functional significance in neonatal rat cardiac myocytes.
