CD3E (CD3 Epsilon Subunit Of T-Cell Receptor Complex) is a Protein Coding gene. Diseases associated with CD3E include Immunodeficiency 18 and T-B+ Severe Combined Immunodeficiency Due To Cd3delta/Cd3epsilon/Cd3zeta. Among its related pathways are Immune response NFAT in immune response and TCR Signaling (Qiagen). Gene Ontology (GO) annotations related to this gene include protein heterodimerization activity and obsolete signal transducer activity. An important paralog of this gene is CD3G.Part of the TCR-CD3 complex present on T-lymphocyte cell surface that plays an essential role in adaptive immune response. When antigen presenting cells (APCs) activate T-cell receptor (TCR), TCR-mediated signals are transmitted across the cell membrane by the CD3 chains CD3D, CD3E, CD3G and CD3Z. All CD3 chains contain immunoreceptor tyrosine-based activation motifs (ITAMs) in their cytoplasmic domain.
