== Function ==

'''Apoptosis protease-activating factor-1''' or '''Apoptosis peptidase-activating factor-1''' (APAF-1) binds to cytochrome c and ATP to form the apoptosome which leads to the recruitment and activation of caspase 9 by cleaving the procaspase 9.  Caspase 9 is involved in executing the apoptosis of cells<ref>PMID:15829969</ref>.

== Disease ==

Inactivation of Apaf-1 is implicated in disease progression and chemoresistance of some malignancies<ref>PMID:15972851</ref>.

== Structural highlights ==

Apaf-1 contains several copies of the WD-40 domain which are involved in binding to cytochrome c<ref>PMID:26014357</ref>., caspase recruitment domain (CARD) and an ATPase domain.
