Related Product Information for
anti-Apaf-1 antibody
Large multi-protein complexes known as the DISC (death inducing signalling complex) and the apoptosome activate the normally inactive caspases through proteolytic processing (1). The formation of these complexes leads to the activation of caspases and the execution of apoptosis (1,2). The apoptosome is a large 700 or 1400 kDa protein complex comprised of Apaf-1 (apoptotic protease activating factor-1), cytochrome c, and dATP (1). Apaf-1 and cytochrome c in the presence of dATP leads to the oligomerization of Apaf-1 and the formation of either the 700 or 1400 kDa complexes (3&4). Once formed the apoptosome activates caspase-9, which in turn activates the effector caspases (1&5). Some researchers have found the 700 kDa apoptosome to be the most effective activator of the effector caspases, when compared to the 1400 kDa apoptosome (3&4). Apaf-1 has also been shown to be a target of regulation by a variety of proteins that include p53, IAPs, heat shock proteins and Smac/Diablo (1&6).

NCBI Summary for Apaf-1
This gene encodes a cytoplasmic protein that initiates apoptosis. This protein contains several copies of the WD-40 domain, a caspase recruitment domain (CARD), and an ATPase domain (NB-ARC). Upon binding cytochrome c and dATP, this protein forms an oligomeric apoptosome. The apoptosome binds and cleaves caspase 9 preproprotein, releasing its mature, activated form. Activated caspase 9 stimulates the subsequent caspase cascade that commits the cell to apoptosis. Alternative splicing results in several transcript variants encoding different isoforms.

UniProt Comments for Apaf-1
APAF: Oligomeric Apaf-1 mediates the cytochrome c-dependent autocatalytic activation of pro-caspase-9 (Apaf-3), leading to the activation of caspase-3 and apoptosis. This activation requires ATP. Isoform 6 is less effective in inducing apoptosis. Monomer. Oligomerizes upon binding of cytochrome c and dATP. Oligomeric Apaf-1 and pro-caspase-9 bind to each other via their respective NH2-terminal CARD domains and consecutively mature caspase-9 is released from the complex. Pro-caspase-3 is recruited into the Apaf-1-pro-caspase-9 complex via interaction with pro-caspase-9. Interacts with APIP. Interacts (via CARD and NACHT domains) with NAIP/BIRC1 (via NACHT domain). By E2F and p53/TP53 in apoptotic neurons. Ubiquitous. Highest levels of expression in adult spleen and peripheral blood leukocytes, and in fetal brain, kidney and lung. Isoform 1 is expressed in heart, kidney and liver. 6 isoforms of the human protein are produced by alternative splicing.
