Mammalian
complex I
is composed of fourteen highly conserved core subunits and additional thirty subunits acquired in the course of evolution. At present, the function of the majority of these supernumerary subunits is poorly understood. In this work, we have studied
NDUFA3
, NDUFA5 and NDUFA12 supernumerary subunits to gain insight into their role in CI activity and biogenesis. Using human cell lines in which the expression of these subunits was knocked down with miRNAs, we showed that they are necessary for the formation of a functional holoenzyme. Analysis of the assembly intermediates in mitochondria depleted for these subunits further suggested that they are required for assembly and/or stability of the electron transferring Q module in the peripheral arm of the CI.
