NADH:ubiquinone oxidoreductase (complex I) catalyzes the transfer of electrons from NADH to ubiquinone (coenzyme Q) in the first step of the mitochondrial respiratory chain, resulting in the translocation of protons across the inner mitochondrial membrane. This gene encodes a complex I assembly factor. Mutations in this gene are a cause of mitochondrial complex I deficiency. [provided by RefSeq, Oct 2009]

A study in humans demonstrated that the NDUFAF4 mRNA showed increased expression in platelets from patients with ST-segment elevation myocardial infarction (STEMI) compared to those with non-STEMI (NSTEMI) [Eicher et al. DOI:10.3109/09537104.2015.1083543].
