分子别名（Synonym）
CD3 epsilon & CD3 gamma, CD3E & CD3G
表达区间及表达系统（Source）
Biotinylated Human CD3E&CD3G Heterodimer Protein, His,Avitag&Tag Free (CDG-H82W3) is expressed from human 293 cells (HEK293). It contains AA Asp 23 - Asp 126 (CD3E) & Gln 23 - Ser 116 (CD3G) (Accession # NP_000724.1 (CD3E) & AAI13831 (CD3G)).
Predicted N-terminus: Asp 23 (CD3E)
蛋白结构（Molecular Characterization）
Biotinylated Human CD3E&CD3G Heterodimer Protein, His,Avitag&Tag Free is produced by co-expression of CD3E and CD3G, has a calculated MW of 18.6 kDa (CD3E) and 14.7 kDa (CD3G). Subunit CD3E is fused with a polyhistidine tag at the C-terminus, followed by an Avi tag and subunit CD3G contains no tag at the C-terminus. The reducing (R) heterodimer protein migrates as 20-24 kDa and 25-28 kDa when calibrated against Star Ribbon Pre-stained Protein Marker due to glycosylation.
标记（Labeling）

背景介绍
T细胞表面糖蛋白CD3δ链与CD3γ链（分别简称CD3D与CD3G或CD3D&CD3G）属于单次跨膜I型膜蛋白。CD3δ链与CD3ε链(CD3E)、CD3γ链、CD3ζ链以及T细胞受体α/β和γ/δ异源二聚体共同构成T细胞受体-CD3复合物。该复合物通过将抗原识别信号偶联至多条细胞内信号转导通路，在免疫应答中发挥核心作用。
