CC -!- FUNCTION: Plays an important role in rhoptry physiology and thus is
CC essential for merozoite invasion of host erythrocytes.
CC {ECO:0000269|PubMed:35140336}.
CC -!- SUBCELLULAR LOCATION: Cytoplasmic vesicle, secretory vesicle, rhoptry
CC membrane {ECO:0000269|PubMed:35140336}; Peripheral membrane protein
CC {ECO:0000269|PubMed:35140336}; Cytoplasmic side
CC {ECO:0000269|PubMed:35140336}. Cell membrane
CC {ECO:0000269|PubMed:19777263}; Peripheral membrane protein
CC {ECO:0000269|PubMed:19777263}. Host cell membrane
CC {ECO:0000269|PubMed:19777263}; Peripheral membrane protein
CC {ECO:0000269|PubMed:19777263}; Cytoplasmic side
CC {ECO:0000269|PubMed:19777263}. Note=Localizes below the host
CC erythrocyte cell membrane (PubMed:19777263). Localizes to the cell
CC membrane of merozoites (PubMed:19777263). In merozoites, localizes to
CC the cytosolic face of the rhoptry bulb membrane (PubMed:35140336).
CC {ECO:0000269|PubMed:19777263, ECO:0000269|PubMed:35140336}.
CC -!- DEVELOPMENTAL STAGE: During parasite asexual blood stages, expressed in
CC trophozoites and at the schizont stage (at protein level).
CC {ECO:0000269|PubMed:19777263}.
CC -!- POLYMORPHISM: The number of deca-peptide repeats in the C-terminus
CC varies across P.falciparum strains (PubMed:19777263). Strain 3D7 has 12
CC copies; Dd2 has 14 copies; Hondura-1, FCC1, FCC2, and T996 have 17
CC copies; and strain D10 and FCR3 have 19 copies (PubMed:19777263).
CC {ECO:0000269|PubMed:19777263}.
CC -!- DISRUPTION PHENOTYPE: Impairs merozoite invasion of host erythrocytes
CC at, or prior to, the formation of the tight junction (PubMed:35140336).
CC Merozoite development and egress following schizont rupture are not
CC affected (PubMed:35140336). Inhibits rhoptry bulb RAP1 processing but
CC not secretion of rhoptry neck proteins RH4 and RON4 (PubMed:35140336).
CC Causes defects in rhoptry morphology which are narrower and more
CC elongated (PubMed:35140336). No defect in microneme secretion
CC (PubMed:35140336). {ECO:0000269|PubMed:35140336}.
CC -!- BIOTECHNOLOGY: Antibodies against CERLI2 severely reduces parasitemia,
CC suggesting that CERLI2 is a potential vaccine candidate.
CC {ECO:0000269|PubMed:19777263}.
