BAK1 Background

Bcl-2 homologous antagonist/killer (BAK) is a protein in humans that is encoded by the BAK1 gene on chromosome 6 [1]. BAK is a member of the Bcl-2 family and contains four Bcl-2 homology (BH) domains: BH1, BH2, BH3, and BH4. In healthy mammalian cells, BAK localizes primarily to the mitochondrial outer membrane (MOM) but keeps in an inactive monomer form. BAK is activated by BH3-only proteins such as BAD under apoptotic stimulation. The activation of pro-apoptotic effector protein BAK induces its oligomerization into proteolipid pores in the MOM [2][3], inducing the MOM permeabilization and cytochrome c release that ultimately triggers apoptosis. Evidence has shown that BAK can form heterogeneous dimers with Bcl-2 or Bcl-xL to inhibit their anti-apoptotic functions [4]. The BAK deficiency was directly responsible for the arrest in cytochrome c release. This capability was normalized to the BAK-deficient cells by the insertion of recombinant BAK into purified mitochondria from these cells [5]. Current evidence indicated that deficiency of BAK expression is closely associated with the occurrence and development of tumors [6], but BAK1 overexpression contributes to neurodegenerative and autoimmune diseases [7]. Gottlieb B et al. found that different BAK1 variants can exist in both diseased and non-diseased abdominal aortic aneurysm (AAA) tissues compared to matching blood samples in the research of studying the role of genetics in AAA [8]. Pataer et al. reported that adenoviral-mediated overexpression of BAK could induce obvious apoptosis in lung and breast cancer cells, which provided a novel therapeutic strategy for cancer treatment [9]. Moreover, many kinds of tumor therapeutic drugs such as perillyl alcohol and γ-interferon, exert their functions through up-regulating BAK expression [10].
