Additional remarks genetic modification | The unsuccessful attempts to disrupt this gene indicate an essential function during asexual blood stage growth. In the paper evidence is presented that: - Secondary structure prediction suggested that the RNA-binding domains of Puf3s consisted of 11 pumilio repeats, similar to those in human Puf-A and yeast Puf6, which are involved in ribosome biogenesis. - Neither pfpuf3 nor pypuf3 could be genetically disrupted, suggesting they may be essential for the intraerythrocytic developmental cycle - Nuclear, nucleolar location - PyPuf3 changed its localization in mosquito and liver stages from nucleolar to cytosolic puncta. - Affinity purification of PTP-tagged variant of PfPuf3 revealed an association with 31 proteins associated with the 60S ribosome, and an enrichment of 28S rRNA and internal transcribed spacer 2 sequences. Taken together, these results suggest an essential function of PfPuf3 in ribosomal biogenesis | ||||||||||||||||||||||||
