Exogenous Agents that Target Transmembrane Domains of Proteins

摘要

Although membrane proteins account for approximately one third of all proteins encoded in the human genome,the functions and structures of their transmembrane domains are much less understood than the water-soluble regions.A major hurdle in studying these transmembrane domains is the lack of appropriate exogenous agents that can be used as specific probes.Despite the daunting challenges,major strides have recently been made in targeting the transmembrane domains of a variety of membrane proteins.High affinity and selectivity have been achieved in model biophysical systems,membranes of bacteria,and mammalian cells.
