Protein Family Models

This family contains integral membrane proteins that are related to Drosophila rhomboid protein Swiss:P20350. Members of this family are found in bacteria and eukaryotes. Rhomboid promotes the cleavage of the membrane-anchored TGF-alpha-like growth factor Spitz, allowing it to activate the Drosophila EGF receptor. Analysis has shown that Rhomboid-1 is an intramembrane serine protease [2][3][4] (EC:3.4.21.105). Parasite-encoded rhomboid enzymes are also important for invasion of host cells by Toxoplasma and the malaria parasite [5].

rhomboid family intramembrane serine protease is a membrane-bound protein that catalyzes regulated intramembrane proteolysis, resulting in the release of functional polypeptides from their membrane anchor
