PF3D7_0934800 cAMP-dependent protein kinase catalytic subunit

Association between PfRab7 and PfPKA-C-HA in vivo is shown at a single stack of image acquisition. The distribution of PfRab7 (red) is revealed with a specific anti-peptide PfRab7 antibody and the distribution of PfPKA-C-HA (green) is revealed with anti-HA antibodies. The association between PfRab7 and PfPKA-C-HA is shown in white. The level of association between Rab7 and PfPKA-C-HA increases as the parasite develops into a multi-nucleated schizont (nuclei shown stained in blue with DAPI). One can observe a subset of PfRab7+ vesicles associated with a subset of PfPKA-C-HA+ structures. The ability of PfRab7 to bind PfPKA-C suggests that it acts somewhat like a PKA-anchor proteins (AKAP), recruiting PKA to early and late endosomes.
