CD3E
Description
The CD3E gene, located on chromosome 11, encodes the epsilon chain of the CD3 complex, a crucial transmembrane protein essential for T cell development, activation, and signaling. The CD3 complex associates with the T cell receptor (TCR) on the surface of T lymphocytes, forming a functional unit responsible for recognizing and responding to antigens. This interaction triggers a cascade of intracellular signaling events, leading to T cell activation and subsequent immune responses.
Associated Diseases
- Severe Combined Immunodeficiency (SCID)
- Autoimmune diseases (e.g., lupus, rheumatoid arthritis)
- Leukemia
- Lymphoma
- Immunodeficiency disorders
Did you know?
Mutations in the CD3E gene can lead to a rare immunodeficiency disorder called CD3 deficiency, characterized by impaired T cell development and function.
