摘要: Membrane proteins which are involved in the signal transmittance through a biological membrane or participate transfer of solutes across cell membranes presumed to span lipid bilayer. The proteins’ transmembrane disposition can be assayed by various techniques including labeling procedures with hydrophilic chemical reagents, enzyme-mediated modifications, protease accessibility and antibody interaction. Convincing evidence for intramembraneous protein arises from hydrophobic studies. Those segments intrinsic that close association hydrocarbon core bilayer may identified using photogenerated reagents (Gitler Bercovici 1980, Brunner Semenza 1981, Ross et al. 1982).
