Protein Structure

UniProt Annotation

Function

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. {ECO:0000269PubMed:10393175, ECO:0000269PubMed:12804598}.

Subcellular Localization

Cytoplasm {ECO:0000269PubMed:12804598}.

Disease Associations

Tissue Specificity

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.
