Question: What is the function of BAX

Context:
pro-apoptotic protein Bax
Bax, a central cell death regulator, is an indispensable gateway to mitochondrial dysfunction and a major proapoptotic member of the B-cell lymphoma 2 (Bcl-2) family proteins that control apoptosis in normal and cancer cells
Thus, PP2A may function as a physiological Bax regulatory phosphatase that not only dephosphorylates Bax but also activates its proapoptotic function.
The ability of the mutants to protect against Bax-mediated cell death is divided into three groups: (1) group I, retention of anti-Bax function in both the Val129 and Met129 mutants; (2) group II, retention of anti-Bax function only in Val129 mutants; and (3) group III, reduction or no anti-Bax function in Val129 and Met129 mutants.
A popular model of BCL-2 and BAX involvement in apoptosis suggests that upon apoptosis induction cytosolic BAX translocates to the mitochondria, where it displays the pro-apoptotic function, which involves its homodimerization.
The purpose of this study was to investigate the expression of the gene coding for the antiapoptotic molecule Bcl-2, the proapoptotic molecule Bax, and the apoptosis executor enzyme caspase-3 in preimplantation renal biopsies (PIB) as markers for delayed graft function.In this prospective single-center study, gene expression levels were evaluated using real-time TaqMan polymerase chain reaction in PIB of kidneys from 72 deceased donors (DDs) and 18 living donors (LDs).CASP3 and BAX expression levels were higher, whereas those of BCL2 were lower, in DD than in LD PIB
The function Bax and/or Bak in constituting a gateway for mitochondrial apoptosis in response to apoptotic stimuli has been unequivocally demonstrated
Bax is a major proapoptotic member of the Bcl2 family that is required for apoptotic cell death.
Bax is a proapoptotic member of the Bcl-2 family of proteins which localizes to and uses mitochondria as its major site of action.
death-promoting Bax protein
The suppressors function through heterodimerization with the death promoters, Bax
Bax- and Bak-mediated apoptosis severely limits adenoviral replication,
Bax a pro-apoptotic member localizes as monomers in the cytosol of healthy cells and accumulates as oligomers in mitochondria of apoptotic cell
Bax and Bak (Bax/Bak) are essential pro-apoptotic proteins of the Bcl-2 family that trigger mitochondrial outer membrane permeabilization (MOMP) in a Bcl-2/Bcl-xL-inhibitable manner.
BAX protein plays a key role in the mitochondria-mediated apoptosis.
The multi-BCL-2 homology domain pro-apoptotic BCL-2 family members BAK and BAX have critical roles in apoptosis. They are essential for mitochondrial outer-membrane permeabili
Members of the Bcl-2 family play key roles as proapoptotic (e.g., Bax) and antiapoptotic (e.g., Bcl-x(L)) regulators of programmed cell death
The Bcl-2 associated X protein (Bax), belonging to the Bcl-2 family, plays a pivotal role in mitochondria-dependent apoptosis. 
The murine proapoptotic protein Bax 
Bax is a pro-apoptotic member of the Bcl-2 family proteins involved in the release of apoptogenic factors from mitochondria to the cytosol.
activated Bax forms large oligomers that permeabilize the outer mitochondrial membrane, thereby committing cells to apoptosis,

Answer: BAX is a central death regulator that controls apoptosis in normal and cancer cells
pro-apoptotic protein Bax
Exact answer: bax promotes Apoptosis
