CD247


T-cell surface glycoprotein CD3 zeta chain also known as T-cell receptor T3 zeta chain or CD247 is a protein that in humans is encoded by the CD247 gene.

Genomics

The gene is located on the long arm of chromosome 1 at location 1q22-q25 on the Crick 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

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.

Interactions

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