Apoptosis: it's BAK to VDAC.
The voltage-dependent anion channel (VDAC) of the mitochondrial outer membrane (MOM; Mannella & Kinnally, 2008)—also known as mitochondrial porin—has long been implicated in regulating the mitochondrial response to certain cell death stimuli (Galluzzi & Kroemer, 2007). This includes a potential role in MOM permeabilization (MOMP) during apoptosis, which is a necessary step in the release of cyt...
متن کاملTo trigger apoptosis, Bak exposes its BH3 domain and homodimerizes via BH3:groove interactions.
The Bcl-2 relative Bak is thought to drive apoptosis by forming homo-oligomers that permeabilize mitochondria, but how it is activated and oligomerizes is unclear. To clarify these pivotal steps toward apoptosis, we have characterized multiple random loss-of-function Bak mutants and explored the mechanism of Bak conformation change during apoptosis. Single missense mutations located to the alph...
متن کاملVitamin K2 Covalently Binds to Bak and Induces Bak-Mediated Apoptosis s
Vitamin K2 (VK2, menaquinone) is known to have anticancer activity in vitro and in vivo. Although its effect is thought to be mediated, at least in part, by the induction of apoptosis, the underlying molecular mechanism remains elusive. Here, we identified Bcl-2 antagonist killer 1 (Bak) as a molecular target of VK2-induced apoptosis. VK2 directly interacts with Bak and induces mitochondrial-me...

متن کاملOn the role of VDAC in apoptosis: fact and fiction.
Research on VDAC has accelerated as evidence grows of its importance in mitochondrial function and in apoptosis. New investigators entering the field are often confounded by the VDAC literature and its many apparent conflicts and contradictions. This review is an effort to shed light on the situation and identify reliable information from more questionable claims. Our views on the most importan...
