AXL 蛋白, Human (D266N, HEK293, His)

AXL protein is a receptor tyrosine kinase that mediates signals by binding to GAS6 and regulates cell survival, proliferation, migration and differentiation. After ligand binding, AXL dimerizes and autophosphorylates, activating downstream molecules, such as PI3 kinase subunits, GRB2, PLCG1, etc. AXL Protein, Human (D266N, HEK293, His) is the recombinant human-derived AXL protein, expressed by HEK293 , with C-10*His labeled tag and D266N, , , , mutation. The total length of AXL Protein, Human (D266N, HEK293, His) is 426 a.a., with molecular weight of 48.9 kDa.

AXL蛋白是一种受体酪氨酸激酶，通过结合生长因子GAS6，作为将信号从细胞外基质转导到细胞质的关键介质，从而调节细胞存活、增殖、迁移和分化等多种生理过程。细胞表面的配体结合诱导 AXL 二聚化和自磷酸化。激活后，AXL 与各种下游信号分子相互作用并诱导其酪氨酸磷酸化，包括 PI3 激酶亚基（PIK3R1、PIK3R2 和 PIK3R3）、GRB2、PLCG1、LCK、PTPN11、CBL、NCK2、SOCS1 和 TNS2。这会触发 GRB2 和磷脂酰肌醇 3 激酶调节亚基的募集，从而导致 AKT 激酶的下游激活。GAS6/AXL 信号轴在各种过程中发挥着关键作用，例如内皮细胞存活、人类自然杀伤细胞发育过程中的最佳细胞因子信号传导、肝再生、促性腺激素释放激素神经元存活和迁移、血小板激活以及血栓反应的调节。此外，AXL 还参与抑制 Toll 样受体 (TLR) 介导的先天免疫反应，并且在微生物感染的情况下，它可能通过 GAS6 与磷脂酰丝氨酸结合而充当拉沙病毒和淋巴细胞性脉络膜脑膜炎病毒的受体。病毒体包膜的表面。
