Recombinant Human Apoptotic protease-activating factor 1 (APAF1), Truncated

Uniprot Id

O14727

Target Species

Human

Target Name

APAF1

Target Full Name

Apoptotic protease-activating factor 1

Target 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.

Target Subcellular Location

Cytoplasm.

Target 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.

Target Research Area

Cancer

Target Synonyms

APAF 1; Apaf-1; APAF_HUMAN; Apaf1; Apoptotic peptidase activating factor 1; Apoptotic protease activating factor 1; Apoptotic protease activating factor; Apoptotic protease-activating factor 1; CED 4; CED4; KIAA0413

Target Background

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.
