CD3 epsilon is an important component of the TCR-CD3 complex on T lymphocytes and promotes TCR-mediated signaling. When APC activates the TCR, CD3 epsilon, together with CD3D, CD3G, and CD3Z, transmits signals across the cell membrane through ITAMs. CD3 epsilon Protein, Human (HEK293, His) is the recombinant human-derived CD3 epsilon protein, expressed by HEK293 , with C-6*His labeled tag.
