Summary: 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]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

NM_001130846.4 → NP_001124318.2 apoptosis-inducing factor 1, mitochondrial isoform AIFsh

Status: REVIEWED

Description

Transcript Variant: This variant (4) lacks several 5' exons but contains an alternate 5' terminal exon, and it thus differs in the 5' UTR and initiates translation at a downstream in-frame start codon, compared to variant 1. The encoded isoform (AIFsh, also known as AIFshort) is shorter at the N-terminus, compared to isoform AIF. This variant can initiate translation at alternative start codons according to protein N-terminal sequencing and in vitro translation studies in PMID:16365034. The 5'-most start codon is represented in this RefSeq.

Description

Transcript Variant: This variant (5) contains an additional internal exon, which results in a distinct 3' coding region and differences in the 3' UTR, compared to variant 1. The encoded isoform (AIFsh2, also known as AIFshort2) has a distinct C-terminus and is shorter than isoform AIF.

Status: REVIEWED

Description

Transcript Variant: This variant (6) lacks an alternate exon in the 5' region, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
