Fig. 8From: An external sensing system in Plasmodium falciparum-infected erythrocytesThe 32–35 kDa region (covering the PfAB4 proteins) of ItG pRBC from 1D SDS-PAGE were excised and in-gel digested with trypsin. The phosphopeptides were enriched using Pierce Magnetic Titanium Dioxide kit and subjected to Oribitrap mass spectroscopy. This enabled the identification of triple phosphorylation sites in the PfAB4 protein at serine 87, serine 91 and serine 92, which is the PfPCNA1 peptide: LCGANEsVVIssKBack to article page
