Tissue-dependent OXPHOS expression. A clustered binomial heat map demonstrating similarity in the expression pattern of OXPHOS which are not included in the 'main OXPHOS cluster' to the expression of genes within this cluster in specific tissues (red). Dissimilarities of OXPHOS genes from the 'main OXPHOS cluster' are indicated in blue. The orange and green rectangles show the two genes groups, (COX7A1 and COX6A2) and (COX7A2, NDUFS4, NDUFC2, NDUFA11 and ATPIF1), respectively. The gray rectangles show brain tissues.

(A) A map of the upstream region of a representative OXPHOS subunit (NDUFA8) tested for TF binding in DNaseI Genomic Footprinting (DGF) sites. X-axis represent the positions in the promoter region, relative to the translation start site (TSS). DGF sites are indicated by blue lines in the upper row and below, all the listed TFs binding to the 1000 bp promoter region are shown, with their ChIP-seq peaks shown as black lines. Note that only TFs with a ChIP-seq peak overlapping a minimum of one DGF are indicated. (B) Representation of the results for all nDNA-encoded OXPHOS genes. X-axis represent the positions in the promoter region, relative to the translation start site (TSS). DGFs are shown by blue lines if they do not overlap with any identified TF-binding peak in the ChIP-seq experiments and in black and blue lines if they overlap with at least one such TF-binding peak. Supplementary Table 1. A list of OXPHOS genes analyzed in this study, following HUGO Committee (HGNC). OXPHOS structural and assembly factors are indicated, along with their Ensemble accession numbers.
