CHCHD4 is essential and evolutionarily conserved. Previously, we have shown CHCHD4 to be a critical regulator of tumour cell growth. Here, we use integrated analysis of our genome-wide CRISPR/Cas9 and SILAC proteomic screening data to delineate mechanisms of CHCHD4 essentiality in cancer. We identify a shortlist of common essential genes/proteins regulated by CHCHD4, including subunits of complex I that are known DRS substrates, and genes/proteins involved in key metabolic pathways. Our study highlights a range of CHCHD4-regulated nuclear encoded mitochondrial genes/proteins essential for tumour cell growth.
