This gene encodes an inhibitor of apoptosis protein (IAP)-binding protein. The encoded mitochondrial protein enters the cytosol when cells undergo apoptosis, and allows activation of caspases by binding to inhibitor of apoptosis proteins. Overexpression of the encoded protein sensitizes tumor cells to apoptosis. A mutation in this gene is associated with young-adult onset of nonsyndromic deafness-64. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2013]
A study in human cadavers demonstrated that the DIABLO was significantly upregulated in postmortem prostate tissues at longer postmortem intervals (96 h and 120 h) compared to a 24 h control, where it functions as a pro-apoptotic gene by binding to IAPs to activate caspases [Tolbert et al. DOI:10.1016/j.gene.2018.06.090]. In contrast, an investigation of human cadaver liver tissues found the DIABLO was down-regulated (-43,816.0875 fold) in decaying samples compared to a 6 h control [Javan et al. DOI:10.1007/S12024-015-9704-6]. A study in mice demonstrated that ethanol exposure induces oxidative stress via NADPH oxidase, leading to Regnase-1-mediated degradation of the DIABLO mRNA, which represses mitochondrial gene MTND6 and complex I function, thereby driving alcoholic cardiomyopathy, while cardiomyocyte-specific overexpression of the DIABLO via AAV9 mitigated these dysfunctions [Zhang et al. DOI:10.1016/J.Redox.2020.101778]. In *Lucilia cuprina*, expressed sequence tag analysis identified numerous mitochondrial protein-coding genes, including cytochrome oxidase subunits and ATP synthase subunits, as highly abundant transcripts in embryonic and larval stages [Lee et al. DOI:10.1186/1471-2164-12-406].
