Intriguing parasites and intramembrane proteases.
نویسنده
چکیده
Rhomboid intramembrane proteases occur throughout the kingdoms of life. In this issue of Genes & Development, Baxt and colleagues (pp. 1636-1646) report that the single proteolytic rhomboid (EhROM1) from Entamoeba histolytica cleaves cell surface galactose-binding or N-acetylgalactosamine-binding (Gal/Gal-NAc) lectins. EhROM1 and lectins colocalize during phagocytosis and receptor capping. EhROM1 is found at the base of the cap rather than in the cap proper, suggesting a role in receptor shedding and implying that EhROM1 is crucial for amoebal infection.

The roles of intramembrane proteases in protozoan parasites.
Intramembrane proteolysis is widely conserved throughout different forms of life, with three major types of proteases being known for their ability to cleave peptide bonds directly within the transmembrane domains of their substrates. Although intramembrane proteases have been extensively studied in humans and model organisms, they have only more recently been investigated in protozoan parasite...
متن کاملLong-term Proposal Report Structural Study of Regulated Intramembrane Proteolysis
Regulated Intramembrane Proteolysis (RIP) is a highly conserved signaling mechanism, where a signaling molecule is cleaved within the lipid bilayer by an intramembrane protease. Traditional wisdom argued that proteolysis requires water; however, in RIP, both the protease and the substrate are integral membrane proteins and the cleavage occurs within the hydrophobic lipid bilayer. It has been mo...
متن کاملSequence-Specific Intramembrane Proteolysis: Identification of a Recognition Motif in Rhomboid Substrates
Members of the widespread rhomboid family of intramembrane proteases cleave transmembrane domain (TMD) proteins to regulate processes as diverse as EGF receptor signaling, mitochondrial dynamics, and invasion by apicomplexan parasites. However, lack of information about their substrates means that the biological role of most rhomboids remains obscure. Knowledge of how rhomboids recognize their ...
متن کاملMolecular & Biochemical Parasitology New insights into parasite rhomboid proteases
The rhomboid-like proteins constitute a large family of intramembrane serine proteases that are present in all branches of life. First studied in Drosophila, these enzymes catalyse the release of the active forms of proteins from the membrane and hence trigger signalling events. In protozoan parasites, a limited number of rhomboid-like proteases have been investigated and some of them are assoc...
متن کاملSharpening rhomboid specificity by dimerisation and allostery.
In this issue of The EMBO Journal, mechanistic analyses of substrate cleavage by rhomboid intramembrane proteases suggest that catalytic efficiency towards natural, transmembrane substrates is allosterically stimulated by initial substrate interaction with an intramembrane exosite, whose formation depends on rhomboid dimerisation. In the realm of intramembrane proteolysis, dimerisation and allo...
