Definition / general
- Also called T cell receptor zeta chain
- Forms T cell-CD3 receptor complex with TCR alpha/beta and gamma/delta heterodimers and CD3-gamma, delta and epsilon (Proc Natl Acad Sci USA 1988;85:9709)
- Couples antigen recognition to several intracellular signal transduction pathways; low expression causes impaired immune response
- Low expression in tumor infiltrating T cells in various disorders - cancer of kidney (Cancer Invest 2004;22:871) and stomach (Cancer 2002;94:1437), Hodgkin’s lymphoma (Blood 1996;88:236); also active tuberculosis (J Infect Dis 2006;194:1385), systemic lupus erythematosus (J Immunol 2002;169:6048, Adv Med Sci 2006;51:181), normal pregnancy but not preeclampsia (Am J Obstet Gynecol 2003;189:843)
- Defects cause primary T-cell immunodeficiency (OMIM 610163)
