Mutant/mutation
The mutant expresses a C-terminal mNeonGreen-tagged version of AP2R-2

Protein (function)
Through a screen, a gene with a domain related to Plasmodium AP2 family proteins (PBANKA_1418100) was identified. This domain is conserved at the C-terminus of eight Plasmodium AP2 family proteins, named ACDC (AP2-coincident domain mainly at the C-terminus) domain. This gene, hereafter referred to as AP2 TF- related gene 2 (AP2R-2) also possesses the domain at the C-terminus of the encoded protein but lacks AP2 domains. 

Phenotype
Fluorescence microscopy using transgenic parasites expressing AP2R-1 as a mNeonGreen-tagged protein showed that it is expressed in the nucleus of female gametocytes.

Additional information

From the Abstract:
'Fluorescence microscopy showed that AP2-G expression was first observed in the parasite 12 h after erythrocyte invasion and peaked at 18 h when sexual features were first manifested in  early gametocytes. Expression of  AP2-G decreased with manifestation of  sex-specific features. Chromatin immunoprecipitation followed by sequencing (ChIP-seq) was performed at peak AP2-G expression and identified over 1000 binding sites in the genome. The main binding motif of the TF predicted from the binding sites was GTACNY. Predicted targets contained a number of genes related to protein biogenesis, suggesting that AP2-G plays a role in establishing a cellular basis required for sexual differentiation. AP2-G binding sites also existed upstream of gametocyte-specific TFs, namely AP2-G2, AP2-FG, and AP2-G itself. Furthermore, the target contained two AP2 TF-related genes. Disruption of  these genes resulted in  the arrest of  ookinete development. These results suggest another role of  AP2-G: activating a  transcriptional cascade to  promote conversion into early gametocytes.'
