Additional remarks phenotype

Mutant/mutation
The mutant expresses a cmyc-tagged (C-terminal) version of PY17X_0215700

The gene was identified in a transcriptome-based approach to identify novel pre-erythrocytic vaccine antigens. A tiling microarray was used to identify P. falciparum genes transcribed at higher levels during liver stage versus sporozoite or blood stages of development.

Expression of the gene is only analysed in liver stages.
The tagged protein was detected in 24h liver stages and localized in parasite cytoplasm.

Additional remarks genetic modificationThe b3D-myc vector for epitope tagging genes of interest was used to generate the Py
myc-tagged transgenic lines of PyPF3D7_0506200, PyPF3D7_1241500, and PyPF3D7_07
30200. Genes without their stop codons, together with approximately 1.5 kb sequence
upstream from the start codon, were amplified by PCR from Py 17XNL genomic DNA and
inserted upstream of the quadruple myc tag in b3D-myc.
The plasmids were subsequently linearized with Psr I and integrated into the Py 17XNL
genome using standard procedures. This integration strategy created two copies of the
target gene, both under the control of the endogenous promoter: the original gene and the
myc epitope-tagged gene.
