abstract：:Type III integral membrane proteins are oriented in the membrane with their C-terminus in the cytoplasm and their N-terminus extracytoplasmic. Such proteins are believed to have an internal hydrophobic sequence that functions both as an uncleaved signal for membrane insertion and also to anchor the protein in the memb...
