pfam11628: TCR_zetazeta (This model is not part of the current CDD release)
T-cell surface glycoprotein CD3 zeta chain
The incorporation of the zetazeta signalling module requires one basic TCR alpha and two zetazeta aspartic acid TM residues. The structure of the zetazeta(TM) dimer consists of a left-handed coiled coil with polar contacts. Two aspartic acids are critical for zetazeta dimerization and assembly with TCR.
