Sideroflexin 1 (SFXN1), a human mitochondrial serine transporter, was also shown to interact with ATAD3A in MCF7 cells, a human breast cancer cell line, identified by co-immunoprecipitation followed by shotgun mass spectrometry (coIP-MS) (Figure 2 #6) [34]. The gene discussed is SFXN1; the disease is breast cancer.
