FIGURE 5.

Schematic representation of co-localization of COX subunit genes and mitochondrial transcription factor genes in a presumed transcription factory. Loops of all 10 genomic loci for the 10 nucleus-encoded COX subunit genes and three genomic loci for mitochondrial transcription factors A and B (Tfam, Tfb1m, and Tfb2m) plus RNA polymerase II and the relevant transcription factors (NRF-1, NRF-2, and others?) are schematically depicted as occupying the same transcription factory in the murine neuronal nuclei.
