Description

The CD3ε chain of the CD3-TCR complex is a type I membrane protein that undergoes conformational change following ligation of the TCR-CD3 complex.  This conformational change leads to exposure of the proline rich sequence in CD3ε and results in recruitment of Nck. It is expressed by all mature T cells and forms a heteromeric complex with CD3 α/β or γ/δ and ζ chains. It is important in T cell development, and deficiency of this gene has been associated with severe immunodeficiency.

Application Notes

Clone APA1/1 recognizes an activation-dependent intracellular epitope of the CD3ε chain. Additional reported applications (for the relevant formats of this clone) include: immunofluorescent staining of paraformaldehyde fixed sections1, in vivo tracking of T cells 2, and Western blotting3. The LEAF purified format is recommended for in vivo studies.
