描述：

FGF Receptor 1 (D8E4) XP®兔单抗 (生物素标记)能够识别内源性水平的总FGF受体1蛋白。该抗体不与其他FGF受体家族成员发生交叉反应。该单克隆抗体是通过用重组蛋白免疫动物而制备的，该重组蛋白是针对人FGF受体1蛋白的羧基末端。该Cell Signaling Technology抗体在最佳条件下与生物素结合。该抗体预期与未结合的FGF Receptor 1 (D8E4) XP® 兔单抗#9740表现出同一物种的交叉反应。成纤维细胞生长因子 (FGFs)通过细胞表面的酪氨酸激酶受体传递信号，对靶细胞产生促有丝分裂和血管生成的效应。已知FGF受体家族有四个成员：FGFR-1 (flg), FGFR-2 (bek, KGFR), FGFR-3和FGFR-4。每个受体都有一个胞外配体结合区、跨膜区和一个胞内激酶区（1）。在结合配体和二聚化之后，受体的特定的酪氨酸位点发生磷酸化（2）。在FGFR-1的羧基端有7个酪氨酸位点能被磷酸化：Tyr463, 583, 585, 653, 654, 730和 766。Tyr653 和Tyr654对激活的FGFR的催化活性十分重要，对信号传导也是必要的(3)。其它的磷酸化酪氨酸位点能够为下游信号分子，如Crk 和PLCγ，提供结合位点(4,5)。

原厂资料：

Specificity / Sensitivity

FGF Receptor 1 (D8E4) XP® Rabbit mAb (Biotinylated) recognizes endogenous levels of total FGF receptor 1 protein. This antibody does not cross-react with other FGF receptor family members.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a recombinant protein specific to the carboxy terminus of human FGF receptor 1 protein.

Description

This Cell Signaling Technology antibody is conjugated to biotin under optimal conditions. The biotinylated antibody is expected to exhibit the same species cross-reactivity as the unconjugated FGF Receptor 1 (D8E4) XP® Rabbit mAb #9740.

Background

Fibroblast growth factors (FGFs) produce mitogenic and angiogenic effects in target cells by signaling through cell surface receptor tyrosine kinases. There are four members of the FGF receptor family: FGFR1 (flg), FGFR2 (bek, KGFR), FGFR3, and FGFR4. Each receptor contains an extracellular ligand binding domain, a transmembrane domain, and a cytoplasmic kinase domain (1). Following ligand binding and dimerization, the receptors are phosphorylated at specific tyrosine residues (2). Seven tyrosine residues in the cytoplasmic tail of FGFR1 can be phosphorylated: Tyr463, 583, 585, 653, 654, 730, and 766. Tyr653 and Tyr654 are important for catalytic activity of activated FGFR and are essential for signaling (3). The other phosphorylated tyrosine residues may provide docking sites for downstream signaling components such as Crk and PLCγ (4,5).
