DESCRIPTION

Also known as AIFM1_HUMAN, AIFM1, AIF, PDCD8. Functions both as NADH oxidoreductase and as regulator of apoptosis (PubMed:20362274, PubMed:23217327, PubMed:17094969). In response to apoptotic stimuli, it is released from the mitochondrion intermembrane space into the cytosol and to the nucleus, where it functions as a proapoptotic factor in a caspase-independent pathway. The soluble form (AIFsol) found in the nucleus induces 'parthanatos' i.e. caspase-independent fragmentation of chromosomal DNA (By similarity). Binds to DNA in a sequence-independent manner (PubMed:27178839). Interacts with EIF3G, and thereby inhibits the EIF3 machinery and protein synthesis, and activates caspase-7 to amplify apoptosis (PubMed:17094969). Plays a critical role in caspase-independent, pyknotic cell death in hydrogen peroxide-exposed cells (PubMed:19418225). In contrast, participates in normal mitochondrial metabolism. Plays an important role in the regulation of respiratory chain biogenesis by interacting with CHCHD4 and controlling CHCHD4 mitochondrial import (PubMed:26004228)., Has NADH oxidoreductase activity. Does not induce nuclear apoptosis., Pro-apoptotic isoform. Monomer (oxidized form). Homodimer (reduced form). Upon reduction with NADH, undergoes dimerization and forms tight, long-lived FADH2-NAD charge transfer complexes (CTC) resistant to oxidation (PubMed:24914854, PubMed:20111043, PubMed:23217327, PubMed:27818101). Also dimerizes with isoform 3 preventing its release from mitochondria (PubMed:20111043). Interacts with XIAP/BIRC4 (PubMed:17967870). Interacts (via N-terminus) with EIF3G (via C-terminus) (PubMed:17094969). Interacts with PRELID1 (PubMed:21364629). Interacts with CHCHD4; the interaction increases in presence of NADH (PubMed:26004228).
