CD3E

HGNC ID: 1674

Target Abstract:

CD3, also known as T3, is a member of the immunoglobulin superfamily and plays a crucial role in antigen recognition, signal transduction, and T cell activation. CD3ε, with a molecular weight of 20 kDa, is one subunit of the CD3 complex, which consists of two CD3ε, one CD3γ, one CD3δ, and one CD3ζ (CD247) subunit. The CD3 complex forms a heterodimer with α/β or γ/δ T cell receptors (TCR). CD3 is expressed on all mature T cells, NKT cells, and some thymocytes.
