EGFR 蛋白, Rat (HEK293, His)

EGFR Protein is a receptor tyrosine kinase that binds to ligands of the EGF family.EGFR Protein is involved in the regulation of NF-kappa-B , RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC and STATs signaling pathways.EGFR Protein has calmodulin binding activity, epidermal growth factor binding activity and epidermal growth factor activating receptor activity.EGFR Protein, Rat (HEK293, His) is the recombinant rat-derived EGFR protein, expressed by HEK293 , with C-His labeled tag.

EGFR 蛋白是一种受体酪氨酸激酶，与 EGF 家族的配体结合，包括 EGF、TGFA/ TGF-alpha、AREG、epigen/EPGN、BTC/betacellulin -纤维素蛋白、表调节蛋白/EREG 和 HBEGF/肝素结合 EGF。这种相互作用启动级联反应，将细胞外信号转化为细胞反应，包括受体同源和/或异源二聚化和关键细胞质残基的自磷酸化。磷酸化受体招募适配蛋白如 GRB2，激活下游信号级联，包括 RAS-RAF-MEK-ERK, PI3激酶-ATK, PLCgamma-PKC 和 STATs 模块。此外，EGFR 可能触发 NF-kappa-B 信号级联，并直接磷酸化 RGS16 等蛋白，激活其 GTPase 活性，可能将 EGF 受体信号传导与 G 蛋白偶联受体信号传导联系起来。此外，EGFR 磷酸化 MUC1，增强其与 SRC 和 CTNNB1/ β -catenin的相互作用。它通过与 CCDC88A/GIV 相互作用，正向调节细胞迁移，将 EGFR 保留在细胞膜配体刺激后，从而促进 EGFR 信号传导，触发细胞迁移。除了其典型功能外，EGFR 还有助于增强学习和记忆能力，并在哺乳动物疼痛信号传导中发挥作用，其异构体 2 可能作为 EGF 作用的拮抗剂。

1. Measured by its ability to bind human EGF-Fc in a functional ELISA.
2. Measured by its binding ability in a functional ELISA. Immobilized EGFR at 1 μg/ml can bind Anti-EGFR antibody, the ED₅₀ of human EGFR protein is 1.873 ng/mL, corresponding to a specific activity is 5.34×10⁵ units/mg.

  Greater than 95% as determined by reducing SDS-PAGE.

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4 or 20 mM PB, 150 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
