Rhomboid protease.
based on mapping to UniProt P09391
Cleaves type-1 transmembrane domains using a catalytic dyad composed of serine and histidine that are contributed by different transmembrane domains.
-!- These endopeptidases are multi-spanning membrane proteins. -!- Their catalytic site is embedded within the membrane and they cleave type-1 transmembrane domains. -!- Important for embryo development in Drosophila melanogaster. -!- Rhomboid is a key regulator of EGF receptor signaling and is responsible for cleaving Spitz, the main ligand of the Drosophila EGF receptor pathway. -!- Parasite-encoded rhomboid enzymes are also important for invasion of host cells by Toxoplasma and the malaria parasite. -!- Belongs to peptidase family S54.
