This gene encodes a flavoprotein essential for nuclear disassembly in apoptotic cells, and it is found in the mitochondrial intermembrane space in healthy cells. Induction of apoptosis results in the translocation of this protein to the nucleus where it affects chromosome condensation and fragmentation. In addition, this gene product induces mitochondria to release the apoptogenic proteins cytochrome c and caspase-9. Mutations in this gene cause combined oxidative phosphorylation deficiency 6 (COXPD6), a severe mitochondrial encephalomyopathy, as well as Cowchock syndrome, also known as X-linked recessive Charcot-Marie-Tooth disease-4 (CMTX-4), a disorder resulting in neuropathy, and axonal and motor-sensory defects with deafness and cognitive disability. Alternative splicing results in multiple transcript variants. A related pseudogene has been identified on chromosome 10. [provided by RefSeq, Aug 2015]
A study in human cadavers demonstrated that the AIFM1 gene was significantly up-regulated (1916.5755 fold) in decaying liver tissues compared to a 6-hour control, as part of the apoptotic thanatotranscriptome investigated using PCR arrays [Javan et al. DOI:10.1007/S12024-015-9704-6]. In a separate porcine model of bromine-induced skin injury, the AIFM1 transcript was identified as a significantly increased signaling component in the 45 s–7 d exposure group, associated with the mitochondrial dysfunction pathway [Price et al. DOI:10.1016/j.toxlet.2008.08.007]. A study in mice demonstrated that the degradation of the AIFM1 mRNA was significantly correlated with the 0-48 hour postmortem interval in heart tissue and in brain tissue when normalized with Caspase-3 DNA [Peng et al. DOI:10.1007/S00414-019-02199-7].
