Harakiri, a Novel Regulator of Cell Death, Encodes a Protein That Activates Apoptosis and Interacts Selectively With Survival-Promoting Proteins BCL-2 and BCL-Xl

Abstract

Programmed cell death is essential in organ development and tissue homeostasis and its deregulation is associated with the development of several diseases in mice and humans. The precise mechanisms that control cell death have not been elucidated fully, but it is well established that this form of cellular demise is regulated by a genetic program which is activated in the dying cell. Here we report the identification, cloning and characterization of harakiri, a novel gene that regulates apoptosis. The product …
