表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）

Human FGF R1, His Tag (FG1-H5223) is expressed from human 293 cells (HEK293). It contains AA Arg 22 - Ile 376 (Accession # P11362-7).

Predicted N-terminus: Arg 22

蛋白結(jié)構(gòu)（Molecular Characterization）

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 41.2 kDa. The protein migrates as 60-90 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

內(nèi)毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

純度（Purity）

>95% as determined by SDS-PAGE.

制劑（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景（Background）

成纖維細(xì)胞生長因子受體1（FGFR1）也稱為堿性成纖維細(xì)胞增長因子受體1，FMS樣酪氨酸激酶，CD331，是一種受體酪氨酸激酶，其配體是成纖維細(xì)胞成長因子家族的特定成員。這種蛋白質(zhì)是幾種成纖維細(xì)胞生長因子受體之一，這些受體是參與細(xì)胞分裂、細(xì)胞生長和成熟調(diào)節(jié)、血管形成、傷口愈合和胚胎發(fā)育等重要過程的相關(guān)蛋白質(zhì)。FGFR1蛋白橫跨細(xì)胞膜，因此蛋白的一端留在細(xì)胞內(nèi)，另一端從細(xì)胞外表面伸出。這種定位允許FGFR1蛋白與細(xì)胞外的特定生長因子相互作用，并接收有助于細(xì)胞對(duì)其環(huán)境作出反應(yīng)的信號(hào)。當(dāng)生長因子附著在FGFR1蛋白上時(shí)，受體會(huì)在細(xì)胞內(nèi)引發(fā)一系列化學(xué)反應(yīng)，指示細(xì)胞發(fā)生某些變化，例如成熟以承擔(dān)特定的功能。FGFR1蛋白被認(rèn)為在神經(jīng)系統(tǒng)的發(fā)育中起著重要作用。這種蛋白質(zhì)也可能有助于調(diào)節(jié)長骨的生長，如手臂和腿部的大骨頭。
