The following gene names and symbols are associated with antigen CD3 across different species:

CD3e molecule, epsilon (CD3-TCR complex) (CD3E)

Other aliases include:

T3E, TCRE, FLJ18683

On the protein level the following designations are being used for antigen CD3:

CD3E antigen, epsilon polypeptide – CD3-epsilon – T-cell surface antigen T3/Leu-4 epsilon chain – T-cell surface glycoprotein CD3 epsilon chain – CD3e antigen, epsilon polypeptide (TiT3 complex) – T-cell antigen receptor complex, epsilon subunit of T3

CD3 fulfills a number of functions:

SH3 domain binding – T cell receptor binding – protein heterodimerization activity – protein kinase binding – receptor signaling complex scaffold activity – receptor signaling protein activity – transmembrane receptor activity

CD3 is relevant to the following processes:

G-protein coupled receptor protein signaling pathway – T cell activation – positive regulation of T cell proliferation – protein complex assembly – regulation of apoptosis – signal complex assembly

Locations for CD3:

T cell receptor complex – external side of plasma membrane – integral to plasma membrane – plasma membrane
