<p>A 16.7 kilodalton membrane protein which is produced in mature, but not early-stage, T-cells has been discovered. The protein has four distinct amphipathic domains, each having an amino acid composition which is predictive of an alpha helical structure that would be stable in a lipid bilayer. Each of these regions is flanked by a relatively polar domain whose amino acid sequence is predictive of B pleat peptide regions. An antibody specific against one of the polar domains can be used to discriminate mature T-cells in a mixed-cell sample.</p> |
