T-cell surface glycoprotein CD3 zeta chain also known as T-cell receptor T3 zeta chain or CD247 (Cluster of Differentiation 247) is a protein that in humans is encoded by the CD247 gene.[1]

Genomics[edit]

The gene is located on the long arm of chromosome 1 at location 1q22-q25 on the Crick (negative) strand. The gene is 87,896 bases in length. The encoded protein is 164 amino acids long with a predicted weight of 18.696 kiloDaltons.

Function[edit]

T-cell receptor zeta, together with T-cell receptor alpha/beta and gamma/delta heterodimers and CD3-gamma, -delta, and -epsilon, forms the T-cell receptor-CD3 complex. The zeta chain plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. Low expression of the antigen results in impaired immune response. Two alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.[2]

Interactions[edit]

CD247 has been shown to interact with Janus kinase 3[3] and Protein unc-119 homolog.[4]
