CD3E protein has predicted functions such as SH3 domain binding and protein heterodimerization, and plays a crucial role in nervous system development and cell adhesion. It is involved in T cell activation, cytokine production and signal transduction. CD3E-CD3G Heterodimer Protein, Mouse (HEK293, Fc) is a recombinant protein dimer complex containing mouse-derived CD3E-CD3G Heterodimer protein, expressed by HEK293 , with C-hFc labeled tag. CD3E-CD3G Heterodimer Protein, Mouse (HEK293, Fc), has molecular weight of ~38-40 kDa.
