KRGG1 function in RNA editing in Trypanosoma brucei.

ABSTRACT: Mitochondrial gene expression in trypanosomes requires numerous multiprotein complexes that are unique to kinetoplastids. Among these, the most well characterized are RNA editing catalytic complexes (RECCs) that catalyze the guide RNA (gRNA)-specified insertion and deletion of uridines during mitochondrial mRNA maturation. This post-transcriptional resequencing of mitochondrial mRNAs can be extensive, involving dozens of different gRNAs and hundreds of editing sites with most of the mature mRNA sequences resulting from the editing process. Proper coordination of the editing with the cognate gRNAs is attributed to RNA editing substrate-binding complexes (RESCs), which are also required for RNA editing. Although the precise mechanism of RESC function is less well understood, their affinity f
