ITGA5 蛋白, Human (HEK293, His)

ITGA5 is a multifunctional receptor that interacts with multiple ligands such as fibronectin, fibrinogen, PLA2G2A, fibrillin-1 (FBN1), IL1B, human metapneumovirus, and soluble CD40LG. ITGA5 recognizes RGD sequences and mediates cell adhesion through different binding sites. ITGA5 Protein, Human (HEK293, His) is the recombinant human-derived ITGA5 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of ITGA5 Protein, Human (HEK293, His) is 954 a.a., with molecular weight of ~130 kDa.

整合素 α-5/β-1 蛋白 (ITGA5:ITGB1) 作为具有多种配体相互作用的多功能受体。ITGA5:ITGB1 识别其配体中的 RGD 序列，充当纤连蛋白和纤维蛋白原的受体，通过不同的结合位点介导细胞粘附。值得注意的是，它在与其经典配体结合位点不同的位点上与 PLA2G2A 结合，从而诱导增强配体结合的构象变化。此外，ITGA5:ITGB1 作为 fibrillin-1 (FBN1) 的受体，促进 RGD 依赖性细胞粘附。它也是纤连蛋白 (FN1) 的受体，使 RGD 依赖性细胞粘附到 FN1。此外，ITGA5:ITGB1 作为 IL1B 受体，在 IL1B 信号传导中发挥着至关重要的作用。在微生物感染的情况下，ITGA5:ITGB1 作为人类偏肺病毒的受体，强调了它参与病原体识别。此外，ITGA5:ITGB3 作为可溶性 CD40LG 的受体，在 CD40/CD40LG 信号传导中发挥着至关重要的作用。这种广泛的配体相互作用强调了 ITGA5:ITGB1 在细胞过程和信号通路中的多功能性。

Approximately 130 kDa

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

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.2.

<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.
