20-aa peptide from mouse AIF.

Mitochondria play a pivotal role in the regulation of programmed cell death or apoptosis. Apoptosis is driven by two classes of specialized proteases known as caspases (Cysteine aspartase). The initiator caspases can be activated by self-cleavage. The effector caspases are then activated in an amplification cascade. Several key participants are released from the mitochondria that regulate apoptosis. The first such factor (Cytochrome-C) to be described binds to a cytoplasmic scaffolding protein called Apaf-1. Binding of the mitochondria factor allows Apaf-1 to form a ternary complex with, and activate, the initiator pro-caspase-9. Active caspase-9 then turns on downstream effector caspases, initiating apoptosis. Another mitochondrial-derived factor, termed Apoptosis inducing factor (AIF), has been identified. AIF is sufficient to induce apoptosis of isolated nuclei. AIF (mouse 612 aa, rat 613 aa, and human 612 aa, chromosome Xq25-q26) is a flavoprotein of ~57kD. It normally resides in the mitochondrial but translocates to the nucleus. AIF induces mitochondrial to release Cytochrome-c and caspase-9. It has been found in liver and many other tissues.

Mouse and human AIF are 92% homologous. The C-terminus of AIF shares significant homology with several bacterial ferredoxins, and the N-terminus has two mitochondrial localization signal. The N-terminal 1-101aa are cleaved to produce mature AIF.
