MEROPS NameROM4 peptidase (Plasmodium-type)
Other namesPfROM4 (Plasmodium sp.)
Name and HistoryThe infectious stage of the malaria parasite Plasmodium falciparum is the merozoite. To invade a host erythrocyte, the merozoite must first bind to host cell receptors. The surface of the merozoite has adhesins called Duffy binding ligand-erythrocyte binding proteins, of which the best characterized is erythrocyte binding antigen 175 (EBA-175). EBA-175 binds erythrocyte surface glycophorin A. The adhesin-glycophorin interaction has to be disrupted prior to host cell invasion, and EBA-175 is shed from the merozoite surface by PfROM4 (O'Donnell et al., 2006). Other adhesins are also shed by PfROM4 (Baker et al., 2006).
