表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）
Mouse CD3E&CD3D Heterodimer Protein, His Tag&Flag Tag (CDD-M5219) is expressed from human 293 cells (HEK293). It contains AA Asp 23 - Asp 108 (CD3E) & Phe 22 - Ala 105 (CD3D) (Accession # P22646-1 (CD3E) & P04235-1 (CD3D)).
Predicted N-terminus: Asp 23 (CD3E) & Phe 22 (CD3D)
蛋白結(jié)構(gòu)（Molecular Characterization）
Mouse CD3E&CD3D Heterodimer Protein, His Tag&Flag Tag is produced by co-expression of CD3E and CD3D, has a calculated MW of 15.1 kDa (CD3E) and 14.3 kDa (CD3D). Subunit CD3E is fused with a polyhistidine tag at the C-terminus and subunit CD3D is fused with a flag tag at the C-terminus. As a result of glycosylation, the heterodimer protein migrates as 18-19 kDa and 25-32 kDa under reducing (R) condition, and 38-47 kDa under non-reducing (NR) condition (SDS-PAGE).

背景（Background）
T細(xì)胞表面糖蛋白CD3δ和CD3ε鏈，也稱為CD3D和CD3E或CD3D和CD34E，是單程I型膜蛋白。CD3D與CD3-ε（CD3E）、CD3-γ和CD3ζ以及T細(xì)胞受體α/β和γ/δ異二聚體一起形成T細(xì)胞受體-CD3復(fù)合物。T細(xì)胞受體-CD3復(fù)合物在將抗原識別與幾種細(xì)胞內(nèi)信號轉(zhuǎn)導(dǎo)通路偶聯(lián)方面起著重要作用。
