From the top 10 MCC-interactors identified in both whole cell lysates and purified mitochondria of human MM cells, we selected to further verify the interaction of MCC with two important regulators of cell survival and proliferation, PARP1 and prohibitin-2 (PHB2, Figure 7D and E) [62–65], by co-immunoprecipitation and Western blot analyses. Here, PHB2 is linked to Miyoshi myopathy.
