Summaries for CD3E Gene

Entrez Gene Summary for CD3E Gene

  • The protein encoded by this gene is the CD3-epsilon polypeptide, which together with CD3-gamma, -delta and -zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T-cell receptor-CD3 complex. This complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. The epsilon polypeptide plays an essential role in T-cell development. Defects in this gene cause immunodeficiency. This gene has also been linked to a susceptibility to type I diabetes in women. [provided by RefSeq, Jul 2008]

GeneCards Summary for CD3E Gene

CD3E (CD3e Molecule) 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 Hematopoietic cell lineage and G-protein signaling N-RAS regulation pathway. GO annotations related to this gene include protein heterodimerization activity and signal transducer activity.

  • Immunodeficiency 18 (IMD18) [MIM:615615]: An autosomal recessive primary immunodeficiency characterized by onset in infancy or early childhood of recurrent infections. The severity is variable, encompassing both a mild immunodeficiency and severe combined immunodeficiency (SCID), resulting in early death without bone marrow transplantation in some patients. Immunologic work-up of the IMD18 SCID patients shows a T cell-negative, B cell-positive, natural killer (NK) cell-positive phenotype, whereas T-cell development is not impaired in the mild form of IMD18. {ECO:0000269 PubMed:15546002, ECO:0000269 PubMed:8490660}. Note=The disease is caused by mutations affecting the gene represented in this entry.
