FGFR-2 alpha (IIIc) 蛋白, Human (Biotinylated, HEK293, His-Avi)

The FGFR-2 α IIIc protein is a tyrosine protein kinase receptor for fibroblast growth factor and is critical for embryonic development, regulating proliferation, differentiation, and apoptosis. Its importance is evident in embryonic patterning, trophoblast function, limb bud development, lung morphogenesis, osteogenesis, and skin development. FGFR-2 alpha (IIIc) Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived FGFR-2 alpha IIIc protein, expressed by HEK293 , with C-His, C-Avi labeled tag.

FGFR-2 α IIIc 蛋白是一种酪氨酸蛋白激酶，作为成纤维细胞生长因子的细胞表面受体，在调节细胞增殖、分化、迁移和凋亡以及胚胎发育中发挥着关键作用。它在正常胚胎模式、滋养层功能、肢芽发育、肺形态发生、成骨和皮肤发育中的不可或缺性是显而易见的。此外，FGFR-2 α IIIc 在成骨细胞分化、增殖和凋亡中发挥着至关重要的作用，对正常骨骼发育有显着贡献。在促进角质形成细胞和未成熟成骨细胞的细胞增殖的同时，它促进分化的成骨细胞的凋亡。配体结合后，FGFR-2 α IIIc 激活多个信号级联反应，包括 PLCG1、FRS2 和 PAK4 的磷酸化。PLCG1 的激活会触发细胞信号分子的产生，例如二酰基甘油和肌醇 1,4,5-三磷酸。FRS2 的磷酸化导致 GRB2、GAB1、PIK3R1 和 SOS1 的募集，介导 RAS、MAPK1/ERK2、MAPK3/ERK1、MAP 激酶信号通路和 AKT1 信号通路的激活。为了调节 FGFR2 信号传导，该蛋白通过泛素化、内化和降解进行下调。导致组成型激酶激活或损害正常 FGFR2 成熟、内化和降解的突变会导致信号传导异常。此外，过表达的 FGFR2 会促进 STAT1 的激活。

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
