PF3D7_1340100 exosome complex component RRP42, putative

Colocalization analysis of the exosomal proteins in the parasite by indirect immunofluorescent assay. The red fluorescence (Alexa Fluor 594) indicates PfDis3 and the green fluorescence (Alexa Fluor 488) indicates PfRrp4, PfRrp41, PfRrp42 and PfRrp6. Scale bar, 5 μm. The colocalization of these components in the periphery of the nucleus indicated that they are essential elements in the complex. However, unlike that of Dis3 in human and yeast, which are mainly nuclear, PfDis3 is only cytoplasmic, indicating that PfDis3 is involved in the composition of the cytoplasmic complex. Further, Rrp6 has previously been considered as the main component of nuclear exosome; PfRrp6, however, appeared in the cytoplasm.
