CD3D
Description
The CD3D gene encodes a protein that is a critical subunit of the T cell receptor (TCR) complex, a complex of proteins essential for the adaptive immune response. TCRs are expressed on the surface of T lymphocytes and recognize specific antigens presented by antigen-presenting cells. The CD3D protein plays a vital role in signal transduction downstream of TCR activation, triggering a cascade of events that ultimately lead to T cell activation, proliferation, and differentiation. Variations in the CD3D gene can affect the function of the TCR complex and contribute to immune dysfunction.

Did you know?
Mutations in the CD3D gene are responsible for a rare form of SCID, a life-threatening condition characterized by an absence of functional T cells.
