分子別名(Synonym)
FOLR2,BETA-HFR,FBP,PL-1,FR-BETA,FR-P3,FBP
表達區(qū)間及表達系統(tǒng)(Source)
Human FOLR2, His Tag (FO2-H5223) is expressed from human 293 cells (HEK293). It contains AA Thr 17 - His 228 (Accession # P14207-1).
Predicted N-terminus: Thr 17
蛋白結構(Molecular Characterization)
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 26.5 kDa. The protein migrates as 30-35 kDa under reducing (R) condition (SDS-PAGE) due to N-linked glycosylation which has been verified by PNGase F digestion.
內毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
純度(Purity)
>90% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in Tris and Glycine, pH7.5 with trehalose as protectant.

背景(Background)
葉酸受體β也稱為葉酸受體2、FBP、FOLR2、beta-HFR、FBP/PL-1、FR-beta、FR-P3,是葉酸受體(FOLR)家族的成員。并介導5-甲基四氫葉酸向細胞內部的遞送。該蛋白分別與FOLR1和FOLR3蛋白具有68%和79%的序列同源性。FOLR2蛋白最初被認為只存在于胎盤中,但也在脾臟、骨髓和胸腺中檢測到。FOLR2主要在胎盤、中性粒細胞譜系細胞和一些CD34+造血祖細胞中表達。它在髓系白血病、頭頸部鱗狀細胞癌和幾種非上皮性癌癥中上調。它也在慢性炎癥部位的巨噬細胞和單核細胞上上調,包括類風濕性關節(jié)炎滑膜和膠質母細胞瘤。FOLR2是M-CSF存在下產生的巨噬細胞的標志物,但不是GM-CSF。其表達與葉酸攝取能力的增強有關。治療藥物的葉酸偶聯(lián)物是靶向腫瘤相關巨噬細胞的潛在免疫治療工具。
