分子別名（Synonym）
TPBG,5T4,M6P1,5T4AG,WAIF1,5T4 oncofetal antigen,Trophoblast glycoprotein,5T4 oncofetal trophoblast glycoprotein
表達區(qū)間及表達系統(tǒng)（Source）
Unconjugated Human TPBG, His,Avitag (TPG-H52E5) is expressed from human 293 cells (HEK293). It contains AA Ser 32 - Ser 355 (Accession # Q13641-1).
Predicted N-terminus: Ser 32
蛋白結(jié)構(gòu)（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag?).
The protein has a calculated MW of 39.0 kDa. The protein migrates as 50-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
應(yīng)用說明（Application）

背景（Background）
滋養(yǎng)層糖蛋白（TPBG），也稱為5T4，是目前臨床開發(fā)的幾種抗癌藥物的治療靶點，主要是由于其在腫瘤中的高表達和在正常成人組織中的低表達。該基因編碼一種富含亮氨酸的跨膜糖蛋白，可能參與細胞粘附。TPBG早在發(fā)育9周時就由所有類型的滋養(yǎng)層細胞表達。
