Mutant/mutation
The mutant expresses a C-terminal mCherry-3xMyc-tagged version of ATP8

Protein (function)
Membrane transport proteins (MTP) transfer compounds across biological membranes and encompass diverse gene families, namely ion channels, ATP-dependent pumps and secondary active porters including those of the major facilitator superfamily. In contrast to bacteria, archaea and fungi, parasitic protozoa such as Trypanosoma brucei and the malaria parasite Plasmodium falciparum allocate only a small proportion of their genomes (2–3%) to membrane transport. P. falciparum encodes at least 122 MTPs. For 39 gene products, functional or subcellular localization predictions remain elusive, rendering them orphan MTPs.
In this study a comprehensive genetic analysis is reported of 35 orphan transport proteins of Plasmodium berghei during its life cycle in mice and Anopheles mosquitoes.

Phenotype
Moderate mCherry expression at the parasite-host interface (as visualized by fluorescence microscopy).

Additional remarks genetic modificationFragments of 400–650 bp in the 3' flanking regions of the genes of interest were amplified by using the 3' fragment forward and reverse primer combinations (3'MTP-F-AvrII and 3'MTP-R-KpnI). The 3' fragments were cloned using the indicated restriction sites into the pBAT-SIL6 vector, resulting in intermediate vectors (pMTP-IM).
For completion of the tagging vectors (pMTP-tag), 400–650 bp fragments at the carboxy-terminal (CT) ends of the coding sequences were amplified using the CT fragment forward and reverse primer combinations (CT-MTP-F-SacII and CTMTP-R-HpaI) and cloned into the pMTP-IM vectors using SacII and HpaI resulting in in-frame fusions of the CT coding regions with the mCherry-3xMyc tag.
