M48 Ste24 endopeptidase-like, integral membrane metallopeptidase
This family contains peptidase M48 family Ste24p-like proteins that are as yet uncharacterized, but probably function as intracellular, membrane-associated zinc metalloproteases; they all contain the HEXXH Zn-binding motif, which is critical for Ste24p activity. They likely remove the C-terminal three residues of farnesylated proteins proteolytically and are possibly associated with the endoplasmic reticulum and golgi. Some members also contain ankyrin domains which occur in very diverse families of proteins and mediate protein-protein interactions.
