abstract

  • Given the key roles of integral membrane proteins as transporters and channels, it is necessary to understand their structures and, hence, mechanisms and regulation at the molecular level. Membrane proteins represent approximately 30% of all proteins of currently sequenced genomes. Paradoxically, however, only approximately 2% of crystal structures deposited in the protein data bank are of membrane proteins, and very few of these are at high resolution (better than 2A). The great disparity between our understanding of soluble proteins and our understanding of membrane proteins is because of the practical problems of working with membrane proteins - specifically, difficulties in expression, purification and crystallization. Thus, computational modeling has been utilized extensively to make crucial advances in understanding membrane protein structure and function.
