What is HMPAS?
  HMPAS is a human membrane protein analysis system containing 36,585 proteins and their important characteristics. It integrates known membrane proteins from 19 different publicly available resources. The collected proteins are classified based on their interaction type with membrane and used them separately to build more accurate prediction rules for the membrane proteins. They are also hierarchically classified based on their subcellular localization and molecular function and integrated with diverse sequence features, biological process and pharmaceutical information. Therefore, HMPAS can provide which types of membrane proteins are currently pharmaceutically targeted and what kinds of characteristic features they have in one place. HMPAS supports a number of interfaces to facilitate users to obtain organized information of the membrane proteins and analyze sequence from user. [More]
