分子別名(Synonym)
KDR,CD309,FLK1,VEGFR,VEGFR2
表達區(qū)間及表達系統(tǒng)(Source)
Human VEGF R2, His Tag (KDR-H5227) is expressed from human 293 cells (HEK293). It contains AA Ala 20 - Glu 764 (Accession # AAI31823.1).
Predicted N-terminus: Ala 20
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 85.2 kDa. The protein migrates as 125-150 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)
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
VEGFR2也稱為CD309,是VEGFR的亞型之一。VEGF受體是血管內(nèi)皮生長因子(VEGF)的受體。VEGFR有三種主要亞型,編號為1、2和3。VEGF受體具有由7個免疫球蛋白樣結(jié)構(gòu)域組成的細胞外部分、一個跨膜區(qū)和一個含有分裂酪氨酸激酶結(jié)構(gòu)域的細胞內(nèi)部分。VEGF-A與VEGFR-1(Flt-1)和VEGFR-2(KDR/Flk-1)結(jié)合。VEGFR-2似乎介導了幾乎所有已知的細胞對VEGF的反應。VEGFR-1的功能不太明確,盡管它被認為可以調(diào)節(jié)VEGFR-2信號傳導。VEGFR-1的另一個功能可能是充當假受體/誘餌受體,將VEGF與VEGFR-2結(jié)合隔離開來(這在胚胎血管生成過程中似乎尤為重要)。此外,VEGFR2能夠在VEGF激活后與HIV-1細胞外Tat蛋白相互作用,似乎可以增強卡波濟氏肉瘤病變中的血管生成。
