VDAC-2 : Mitochondrial outer membrane regulator masquerading as a channel?
© 2015 Federation of European Biochemical Societies..
The voltage-dependent anion channels (VDACs) are the workforce of mitochondrial transport and as such are required for cellular metabolism. The elaborate interplay between mitochondria and the apoptotic pathway supports a role for VDACs as a major regulator of cell death. Although VDAC-1 has an established role in apoptosis and cell homeostasis, the role of VDAC-2 has been controversial. In humans, VDAC-2 is best known for its anti-apoptotic properties. In this Viewpoint, we associate the various functional studies on VDAC-2 with structural reports, to decode its unique behavior. The well-structured N-terminus, compact barrel form, differences in the loop regions, specific transmembrane segments and the abundance of thiols in VDAC-2 enable this isoform to perform a different subset of regulatory functions, establish anti-apoptotic features and contribute to gametogenesis. VDAC-2 structural features that demarcate it from VDAC-1 suggest that this particular isoform is better suited for regulating reactive oxygen species, steroidogenesis and mitochondria-associated endoplasmic reticulum membrane regulatory pathways, with ion transport forming a secondary role. A better understanding of the unique structural features of the VDAC family will aid in the design of inhibitors that could alleviate irregularities in VDAC-controlled pathways.
