AXL 蛋白, Cynomolgus (417a.a, HEK293, His)

AXL Protein, a receptor tyrosine kinase, mediates signals by binding GAS6, regulating cell survival, proliferation, migration, and differentiation. Upon ligand binding, AXL undergoes dimerization and autophosphorylation, activating downstream molecules like PI3-kinase subunits, GRB2, PLCG1, and more. This triggers AKT kinase activation, influencing processes such as endothelial cell survival, cytokine signaling in NK cell development, hepatic regeneration, gonadotropin-releasing hormone neuron function, platelet activation, thrombotic responses, and immune modulation. AXL also serves as a receptor for lassa virus and lymphocytic choriomeningitis virus during microbial infection. AXL Protein, Cynomolgus (417a.a, HEK293, His) is the recombinant cynomolgus-derived AXL protein, expressed by HEK293 , with C-His labeled tag. The total length of AXL Protein, Cynomolgus (417a.a, HEK293, His) is 417 a.a., with molecular weight of 68-70 kDa.

AXL 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，它作为拉沙病毒和淋巴细胞性脉络膜脑膜炎病毒的受体，可能是通过 GAS6 与病毒粒子包膜表面的磷脂酰丝氨酸结合而发挥作用^[1][2][3][4]。
