特技
人FGF-19是由FGF19基因编码的。FGF-19属于FGF-19亚家族，FGF-19有三个成员，21, 23个。FGFs通常被认为是旁分泌因子，它们在胚胎发育过程中在组织图案化和器官发生中起着重要作用。相比之下，FGF-19亚家族最近已被证明以内分泌方式发挥作用。该亚家族成员与肝素结合位点的结合能力差，这是配体-受体复合物形成的关键因素。β-Klotho已被鉴定为FGF-19，21, 23信号转导所需的共同因子。可明显增加配体受体亲和力。与大多数FGFs结合和激活一个以上的FGF受体，FGF19是FGFR4的特异性配体。在FGF-19转基因小鼠中，可以观察到降低肝脏甘油三酯、增加脂肪酸氧化、降低葡萄糖水平和改善胰岛素敏感性。

概述
Human FGF-19 is encoded by the FGF19 gene. FGF-19 belongs to the FGF-19 subfamily which has three members FGF-19, 21, 23. FGFs are classically considered to be paracrine factors and are known for their roles in tissue patterning and organogenesis during embryogenesis. By contrast, the FGF-19 subfamily has recently been shown to function in an endocrine manner. Members of this subfamily have poor ability of binding to heparin binding site which is a crucial factor in ligand-receptor complex formation. β-Klotho has been identified as co-factor required for FGF-19, 21, 23 signaling. It can obviously increase ligand-receptor affinity. Unlike most FGFs which bind to and activate more than one FGF receptor, FGF19 is a specific ligand for FGF R4. In FGF-19 transgenic mice, reducing liver triglycerides, increasing fatty acid oxidation, reducing glucose levels and improving insulin sensitivity can be observed.
