CountryUSA
Name of the mutant parasite
RMgm numberRMgm-124
Principal name∆PbCCp1/∆PbCCp3
Alternative name952 m1-m0cl1
Standardized name
Is the mutant parasite cloned after genetic modificationYes
Phenotype
Asexual blood stageNot different from wild type
Gametocyte/GameteNot different from wild type
Fertilization and ookineteNot different from wild type
OocystNormal numbers of oocysts are produced. Sporozoite formation within the oocysts is blocked. Analysis of the morphology of oocysts by light microscopy revealed that the majority of 17–22 day oocysts were either vacuolated or non-sporulated, and did not contain sporozoites.
SporozoiteNo hemocoel and salivary gland sporozoites were detected.
Liver stageNot tested
Additional remarks phenotype

Mutant/mutation
The mutant lacks expression of two proteins CCp1 (LAP2, LCCL/lectin adhesive-like protein 2; LCCL domain containing protein CCp1) and CCp3 (PbSR, P. berghei Scavenger Receptor-like protein; PSLAP; LAP1).

Protein (function)
The ccp1 and ccp3 genes are members of a small conserved gene family, encoding proteins with multiple adhesive domains, for example a Lgl1 (LCCL)-lectin adhesive domain. In P. falciparum the LCCL domain-containing proteins are termed PfCCp's and in P. berghei PbLAP's.

Phenotype
Phenotype analyses indicate a role during oocyst development and sporozoite formation/production (see also additional information).

Additional information
In another study (Raine, J.D. et al., 2007, PloS Pathogens 3, e30) it has been shown that crossings of ∆lap2 (ccp1) and ∆lap1  (pbsr/ccp3) mutant females with wild type males did not rescue the formation of sporozoites. In contrast, crossing of the mutant males with wild type females resulted in wild type production of sporozoites that were infectious to C57BL/6 mice.
The lack of rescue of the mutant phenotypes by crossing of mutant females with wild type males is suggestive of a role of these proteins within a few hours after fertilisation.

Other members of the LAP/CCp family of proteins have been analysed by targeted gene disruption. A number of mutants lacking expression of these proteins show a comparable defect in development of oocysts and formation of sporozoites (RMgm-113, RMgm-114, RMgm-115: LAP1/PbSLAP/PbSR/CCp3; RMgm-119: LAP4/CCp2; RMgm-98: LAP5/FNPA; RMgm-120: LAP6, CCp4).

RMgm-121: A mutant lacking expression of LAP2/CCp1
RMgm-113: A mutant lacking expression of PbSR/PSLAP/LAP1/CCp3
RMgm-114: A mutant lacking expression of PbSR/PSLAP/LAP1/CCp3
RMgm-115: A mutant lacking expression of a mutated form of PbSR/PSLAP/LAP1/CCp3
RMgm-125: A mutant lacking expression of both LAP2/CCP1  and LAP6/CCp4

Selection (positive) procedurepyrimethamine
Selection (negative) procedureNo
Additional remarks genetic modificationThe ccp1/lap2 gene has been disrupted using a construct that contains the tgdhfr selectable marker and that integrates by double cross-over recombination. This mutant line (429cl1) has been described as mutant RMgm-121. The ccp3 (pbsr, lap1) gene has been disrupted in this line.
The ccp3 gene has been disrupted using a construct that integrates by single cross-over integration (insertion vector) that contains the hdhfr selectable marker. The disadvantage of using an insertion construct is that the construct can be removed from the genome, thereby restoring the wild type genotype.

Additional remarks genetic modificationThe construct to disrupt the ccp3 (pbsr, lap1) gene has been introduced into the genome of mutant 429cl1 (RMgm-121) that contains a disrupted ccp1/lap2 gene and the tgdhfr selectable marker.
The ccp3 gene has been disrupted using a construct that integrates by single cross-over integration (insertion vector) that contains the hdhfr selectable marker. The disadvantage of using an insertion construct is that the construct can be removed from the genome, thereby restoring the wild type genotype.
Additional remarks selection procedureBecause the mutant contained the tgdhfr selectable marker in its genome (used to disrupt the ccp1/lap2 locus) the ccp3 gene has been disrupted using a construct that contains the hdhfr selectable marker that provides resistance against WR99210.
