===Crystal structure of an apoptosis-inducing factor, mitochondrion-associated, 1 (AIFM1) from Homo sapiens at 1.88 A resolution=== | |||
==Disease== | |||
[[http://www.uniprot.org/uniprot/AIFM1_HUMAN AIFM1_HUMAN]] Defects in AIFM1 are the cause of combined oxidative phosphorylation deficiency type 6 (COXPD6) [MIM:[http://omim.org/entry/300816 300816]]. It is a mitochondrial disease resulting in a neurodegenerative disorder characterized by psychomotor delay, hypotonia, areflexia, muscle weakness and wasting.<ref>PMID:20362274</ref> <ref>PMID:22019070</ref> | |||
==Function== | |||
[[http://www.uniprot.org/uniprot/AIFM1_HUMAN AIFM1_HUMAN]] Probable oxidoreductase that has a dual role in controlling cellular life and death; during apoptosis, it is translocated from the mitochondria to the nucleus to function as a proapoptotic factor in a caspase-independent pathway, while in normal mitochondria, it functions as an antiapoptotic factor via its oxidoreductase activity. The soluble form (AIFsol) found in the nucleus induces 'parthanatos' i.e. caspase-independent fragmentation of chromosomal DNA. Interacts with EIF3G,and thereby inhibits the EIF3 machinery and protein synthesis, and activates casapse-7 to amplify apoptosis. Plays a critical role in caspase-independent, pyknotic cell death in hydrogen peroxide-exposed cells. Binds to DNA in a sequence-independent manner.<ref>PMID:17094969</ref> <ref>PMID:19418225</ref> <ref>PMID:20362274</ref> | |||
