Abstract

In this study the impact of hUPF1 and hUPF2 knockdown on alternative splicing (AS) isoforms of different genes encoding subunits of respiratory chain complex I and complex IV is described. As expected, loss of both hUPF1 and hUPF2 led to impairment of nonsense-mediated mRNA decay (NMD) and accumulation of PTC-containing NMD substrates generated by both complex I and complex IV genes. The levels of some complex I splice variants, which did not contain PTC as well as the level of some complex I canonical transcripts were, however, affected only by hUPF1 knockdown. This finding confirms that NMD plays a role in the maintenance of the transcriptome integrity and reveals a specific impact of hUPF1 on the regulation of complex I genes.
