Additional remarks phenotype

Mutant/mutation
The mutant expresses a C-terminal mCherry-tagged version of CCp2 and a C-terminal GFP-tagged version of Dhc1. The mutant does not contain a drug-selectable marker.

This mutant was generated by crossing of a mutant expressing mCherry-tagged CCp2 in female gametocytes (RMgm-4475) with a mutant expressing GFP-tagged Dhc1 in male gametocytes (RMgm-4476),

For generation of the mutants expressing mCherry-tagged CCp2 and GFP-tagged Dhc1 the CRISPR/Cas9 method was used as described for mutants RMgm-1095 and RMgm-4071.

Protein (function)
The lap4 (ccp2) gene is a member of a small conserved gene family (6 genes), 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. CCp2 is a female specific protein, transcribed/expressed in female gametocytes, ookinetes and young gametocytes

Dhc1 is a a male gametocyte/gamete-specific dynein heavy chain protein

Phenotype
CCp2::mCherry expression in female gametocytes
Dhc1::GFP expression in male gametocytes/gametes

Additional information
In P. berghei transcripts of ccp2 are under translational control in female gametocytes. The protein is only expressed after activation of gametocytes (in gametes/zygotes/ookinetes). In the mutants described here the mCherry-tagged version of P. yoelii ccp2 is expressed as a protein in female gametocytes.
