| Outline of Final Research Achievements |
This study identified a novel candidate of small ORFs (uORF13) that is located within untranslated regions of human messenger RNAs and encodes functional proteins. The uORF13-encoding protein (uORF13p) is localized at mitochondria and seems to be involved in regulation of the membrane potential. Alanine-scanning mutagenesis allowed us to find two different peptide motifs, which can have opposite roles in the membrane potential control. In addition to our first example of functional protein-encoding small ORF located in noncoding regions, this finding also supports that the human genome encodes more functional proteins which we have yet to discover.
