APAF1

A gene on chromosome 12q23.1 that encodes a cytoplasmic protein, which initiates apoptosis. Apoptotic peptidase-activating factor 1 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, APAF-1 forms an oligomeric apoptosome, which binds and cleaves caspase-9 preproprotein, releasing the activated form, which stimulates the caspase cascade that commits the cell to apoptosis.

In the present study, we found that LPS significantly elevated apoptosis-related gene expression, including PI3K and AKT, as well as Cyto-C, Apaf1, caspase-9, and caspase-3 (Figures 4(a)-4(f)).

It has been demonstrated that interdigital cells and thymocytes obtained from mice lacking the caspase activator Apaf1 undergo necroptosis instead of apoptosis [43].

Necroptosis: molecular signalling and translational implications

Changes of mitochondrial transition pore opening, decreased mitochondrial membrane potential, CL oxidation, and the release of proapoptotic cytochrome c and Apaf1 molecules are necessary for the execution of the intrinsic mitochondrial apoptotic pathway [140, 141].
