Abstract
MRP1 and MRP2 are multifunctional mitochondrial RNA-binding proteins with a regulatory role in RNA editing and putative role(s) in RNA processing in Trypanosoma brucei. Silencing of MRP1 and/or MRP2 by RNA interference affected the assembly and functionality of respiratory complexes. The absence of several subunits of complexes I, III and IV resulted in their disintegration and subsequent decrease of specific activities and also caused a significant decrease of membrane potential. The overall respiration in the interfered cells decreased by only about 20%, since the trypanosome alternative oxidase effectively replaced the missing cytochromes and became the principal terminal oxidase.
