CD3e molecule, epsilon also known asCD3E is apolypeptide which in humans is encoded by theCD3Egene which resides on chromosome 11.[5][6]

Function

[edit]

The protein encoded by this gene is the CD3-epsilon polypeptide, which together with CD3-gamma, -delta and -zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms theT cell receptor-CD3 complex. This complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. The epsilon polypeptide plays an essential role in T-cell development.[7]

Clinical significance

[edit]

Defects in this gene cause severeimmunodeficiency.[8][9] This gene has also been linked to a susceptibility to type I diabetes in women.[10]

Interactions

[edit]

T-cell surface glycoprotein CD3 epsilon chain has been shown tointeract withTOP2B,[11]CD3EAP[12] andNCK2.[13]
