Multiple site-specific infrared dichroism of CD3-zeta, a transmembrane helix bundle.


The structure of the transmembrane domain of CD3-zeta a component of the T-cell receptor involved in signal transduction, has been studied in its native state (a lipid bilayer) by multiple site-specific infrared dichroism. For the first time, the transmembrane domain has been labelled at multiple positions along the sequence, representing a total of 11… (More)
