Additional remarks partial/complete disruption
Selectable marker used to select the mutant parasitepbdhfr
Promoter of the selectable markerpbdhfr
Selection (positive) procedurepyrimethamine
Selection (negative) procedureNo
Additional remarks genetic modificationIn this study no details are provided on the DNA construct used to target the tramp gene nor details on primeres used to amplify the 3'and 5' target regions.

See also RMgm-505 for independent unsuccessful attempts to disrupt the P. berghei tramp gene

In this study the protein has been localised in the micronemes of P. berghei merozoites.

However, the P. falciparum ortholog (PfTRAMP) localizes in the rhoptries. See Siddiqui et al, 2013 Cell Microbiol).
