Apoptotic Protease Activating Factor 1 (Apaf-1)–Independent Cell Death Suppression by Bcl-2
Reportedly, antiapoptotic Bcl-2 family proteins suppress apoptosis by binding to and inhibiting members of the CED-4 family of caspase activators. To explore this question, we used embryonic stem (ES) cells in which one (-/+) or both (-/-) copies of the gene encoding apoptotic protease activating factor 1 (Apaf-1), a CED-4 homologue, were disrupted by homologous recombination. Stable clones of ...
متن کاملAPAF 1 ( Apoptotic protease activating factor 1 )
Five isoforms of APAF1 cDNA have been identified in Homo sapiens: The original APAF1 (also called Apaf-1S) is 3585 bp long (it contains 12 WD40 repeats); The APAF1-1M isoform (3618 bp) contains an insertion of 33 nt after position 295 of the first published sequence (11 aa insertion GKDSVSGITSY between aa 98 and 99; it also contains 12 WD40 repeats); The APAF1XS isoform (3516 bp) contains the s...
متن کاملApoptotic protease-activating factor 1 (Apaf-1) as a liable gene for spontaneous mutations in vitro
The apoptotic protease-activating factor 1 (Apaf-1) receives the death signal in the intrinsic ormitochondrial pathway of apoptosis. Upon the releasing of cytochrome c from theintermembrane space of mitochondria and binding to Apaf-1 molecules, a heptamericapoptosome complex is formed and triggers the downstream cascade of caspases. Here, for thefirst time we present spontaneous mutations and r...
متن کاملPro-apoptotic Apoptosis Protease–activating Factor 1 (Apaf-1) Has a Cytoplasmic Localization Distinct from Bcl-2 or Bcl-x
How Bcl-2 and its pro-survival relatives prevent activation of the caspases that mediate apoptosis is unknown, but they appear to act through the caspase activator apoptosis protease–activating factor 1 (Apaf1). According to the apoptosome model, the Bcl-2–like proteins preclude Apaf-1 activity by sequestering the protein. To explore Apaf-1 function and to test this model, we generated monoclon...
