Summary of CCp/LAP expression and phenotype in Plasmodium
P. berghei/P. yoelii | P. falciparum | ||||
---|---|---|---|---|---|
Accession no. | Subcellular localization | Function or KO phenotype | Subcellular localization | Function or KO phenotype | |
CryPH | PBANKA_0704900 | Crystalloid body | CryPH is dispensable for ookinete, oocyst, sporozoite formation | ND | ND |
PfCCp1/PbLAP2 | PBANKA_1300700 | Gametocyte cytoplasm and crystalloid body in ookinetes [26] | LAP2 knockout parasites form oocysts in the normal number, but fail to produce sporozoites inside [35] | Female gametocyte surface (punctate pattern) [31] | |
PfCCp2/PbLAP4 | PBANKA_1319500 | Crystalloid body in developing ookinetes [27] | LAP4 is essential for oocyst maturation and sporozoite formation [35] | Female gametocyte surface (punctate pattern) [31] | In CCp2 deficient parasites, oocyst formation is normal but sporozoites were unable to invade salivary glands [29] |
PfCCp3/PbLAP1 (PbSR) | PBANKA_1035200 | Crystalloid body in developing ookinetes [14] | PbSR is involved in crystalloid formation. It is dispensable for the oocyst formation but essential for sporozoite formation inside [14, 33] | Female gametocyte surface (punctate pattern) [31] | CCp3 deficient mutant lacks CCp1 and CCp2. Sporozoites form normally in oocysts, however they lost abilities of release into hemocoel and invasion of salivary glands [29] |
PfCCp4/PbLAP6 | PBANKA_0417600 | Crystalloid body in developing ookinetes [27] | LAP6 is essential for oocyst maturation and sporozoite formation [35] | Female gametocyte surface (homogenous expression) [31] Co-localized with Pfs230 | CCp4 is dispensable for parasite development in the mosquito vector [31] |
PfCCp5/PbLAP3 | PBANKA_0204500 | Gametocyte cytoplasm and crystalloid body in ookinetes [26] | LAP3 is essential for crystalloid body formation, and for oocyst maturation to produce sporozoites [67] | Female gametocytes (at the pole) [31] | |
PfFNPA/PbLAP5 | PBANKA_1315300 | Crystalloid body in developing ookinetes [27] | LAP5 knockout parasites form oocysts in the normal number, but fail to produce sporozoites inside [36] | Female gametocytes (at the pole) [31] |
