Two Forms of the T-cell Receptor Gamma Protein Found on Peripheral Blood Cytotoxic T Lymphocytes

Nature. 1987 Feb 19-25;325(6106):689-94. doi: 10.1038/325689a0.


The T-cell receptor (TCR) gamma polypeptide is expressed associated with CD3 (T3) on the surface of normal human peripheral blood lymphocytes. These cells function as non-MHC-restricted cytotoxic T lymphocytes (CTL)and thus may play an important role in host immune defence. The TCR gamma polypeptide occurs as a dimer in at least two molecular forms based on the absence or presence of disulphide linkage. These forms use TCR gamma polypeptides with strikingly different peptide backbone sizes.
