Mutant/mutation
The mutant expresses a C-terminal 3xHA-mCherry-tagged version of Ap2-D

Protein (function)
Most sequence-specific transcription factor families found in other eukaryotes seem to be absent from Plasmodium. Instead, an expansion of a protein family containing one or more apetala2 (AP2) DNA-binding domains was observed across the phylum apicomplexa. In total, 27 members of this family have been found in the human malaria parasite Plasmodium falciparum (although a possible 28th member of the family may be present. In total, 26 of these have syntenic orthologs in rodent malaria species, each with its unique stage-specific expression profile.

Phenotype
mCherry expression was detectable in the blood stages of the parasite. The Ap2-D-specific mCherry signal colocalized with cytoplasmic and nuclear localization patterns. No fluorescence was detected in the mosquito or liver stages of the parasites

Analysis of a mutant lacking expression of Ap2-D (RMgm-5582) showed the following:
No phenotype detected throughout the complete lifecycle different from wild type parasites.(see also P. berghei mutant RMgm-2638 for successful knocking out AP2-D and P. berghei/P. yoelii mutants RMgm-4100 and RMgm-4372 for unsuccessful attempts to knockout this gene).

Additional information
From the paper:
Using a conserved domain (NCBI CDD) search, we found that amino acids ranging from glycine 185 to isoleucine 228 at the C-terminus have an Ap2 DNA binding domain.
