Human CD3 epsilon&CD3 gamma Heterodimer Protein, His Tag&Tag Free (MALS verified)

分子别名（Synonym）

CD3 epsilon & CD3 gamma,CD3E & CD3G

表达区间及表达系统（Source）

Human CD3E&CD3G Heterodimer Protein, His Tag&Tag Free (CDG-H52W5) is expressed from human 293 cells (HEK293). It contains AA Asp 23 - Asp 126 (CD3E) & Gln 23 - Ser 116 (CD3G) (Accession # P07766-1 (CD3E) & P09693-1 (CD3G)).

Predicted N-terminus: Asp 23 (CD3E) & Gln 23 (CD3G)

蛋白结构（Molecular Characterization）

Human CD3E&CD3G Heterodimer Protein, His Tag&Tag Free is produced by co-expression of CD3E and CD3G, has a calculated MW of 16.9 kDa (CD3E) and 14.6 kDa (CD3G). Subunit CD3E is fused with a polyhistidine tag at the C-terminus and subunit CD3G contains no tag at the C-terminus. The reducing (R) heterodimer protein migrates as 19 kDa and 21-28 kDa when calibrated against Star Ribbon Pre-stained Protein Marker due to glycosylation.

背景（Background）

T-cell surface glycoprotein CD3 delta & CD3 gamma chain, also known as CD3D & CD3G or CD3D&CD3G respectively, are single-pass type I membrane proteins. CD3D, together with CD3- epsilon(CD3E) , CD3-gamma and CD3-zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T cell receptor-CD3 complex. T cell receptor-CD3 complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways.
