Selection (negative) procedureNo
Additional remarks genetic modificationDisruption experiments were performed in the Leiden Malaria Research Group
(exp. 722, 747, 760; pl109).

The unsuccessful attempts to disrupt this gene indicates an essential function during blood stage development.

See also RMgm-552 for unsuccessful attempts to disrupt PBANKA_091210

Disruption of the P. falciparum ortholog has been attempted (Solyakov et al., 2011, Nat Commun, 2:565).
The gene is likely essential for asexual proliferation as integration of the KO vector was not achieved. Accesibility of the locus to recombination was verified by C-terminal tagging.
