PANK1 and malaria: Our observations that the PanK activity of the immunoprecipitated PfPanK complex (Fig 2B(ii)), which includes the presence of PfPanK2 (as well as, potentially, additional proteins), is indistinguishable from the PanK activity of parasite lysates (Fig 2B(i)), is consistent with the PfPanK complex described here being responsible for the malaria parasite’s PanK activity.
