STARD7 and breast cancer: As an evidence linking the phenotype of STARD7‐depleted breast cancer cells with a mitochondrial function of STARD7, interactomic studies carried out with mitochondrial proteins identified an interaction between STARD7 and several candidates, including CHCHD10.[43] Interestingly, CHCHD10 protein levels were strongly downregulated in breast cancer cells lacking STARD7, as demonstrated through our proteomic studies, suggesting that STARD7 may bind and stabilize CHCHD10.
