WDR26/MIP2 interacts with VDAC1 and regulates VDAC1 expression levels in H9c2 cells

Free Radical Biology and Medicine, 2018
MIP2, one of WDR26 isoforms, encodes a 498 amino acid protein with an amino-terminal CTLH domain and five carboxyl-terminal WD40 motifs. MIP2 is localized to the mitochondria and protects cardiomyocytes against oxidative stress; however, nothing is known about how MIP2 confers its cytoprotection.

Dominant-negative VDAC1 mutants reveal oligomeric VDAC1 to be the active unit in mitochondria-mediated apoptosis

Biochemical Journal, 2010
Mitochondria play a central role in the intrinsic pathway of apoptosis. Oligomerization of the mitochondrial protein VDAC1 (voltage-dependent anion channel 1) has been proposed to play a role in apoptosis in various studies. In the present study, we have generated dimeric fusion proteins consisting of tandem-linked wild-type and RuR (Ruthenium Red ...

Characterization of VDAC1 as a plasma membrane NADH‐oxidoreductase

BioFactors, 2004
AbstractWe have recently demonstrated that voltage dependent anion selective channel 1 (porin, isoform 1) can function as a transplasma membrane NADH:ferricyanide‐reductase. However, both the specific redox characteristics and the mechanism of electron transport in this enzyme presently remain unclear.

ANP32B promotes lung cancer progression by regulating VDAC1

Gene, 2023
It has been reported before that acidic leucine-rich nuclear phosphoprotein 32 family member B (ANP32B) plays roles in many cancers, yet no report of its role in lung cancer exists. In this study, we documented an elevation of ANP32B within lung cancer tissues and cells. Knockdown of ANP32B hindered the proliferation as well as migration of lung cancer

VDAC1: at the crossroads of cancer signalling and metabolism

Expert Review of Proteomics
Mitochondrial membrane proteins are key regulators of mitochondrial physiology and function. Voltage-dependent anion channel 1 (VDAC1), also termed mitochondrial porin, regulates metabolite and ion exchange across the outer mitochondrial membrane. It governs mitochondrial bioenergetics, apoptotic signaling, redox balance, and intracellular calcium ...

Purification of VDAC1 from Rat Liver Mitochondria

Cold Spring Harbor Protocols, 2013
To make biophysical measurements of functions such as the pore-forming activity of mitochondrial voltage-dependent anion-selective channel protein 1 (VDAC1), it is first necessary to obtain a source of purified VDAC protein. In this protocol, we present a method for obtaining rat liver mitochondria as a source of VDAC1 and then describe two methods ...

In silico construction of HK2-VDAC1 complex and investigating the HK2 binding-induced molecular gating mechanism of VDAC1

Mitochondrion, 2016
Hexokinase 2 (HK2) binds to Voltage-Dependent Anion Channel 1 (VDAC1) on mitochondrial outer membrane (MOM) to facilitate a preferential access of ATP to HK2 for glycolysis, in order to maintain a constant energy source for cell proliferation in cancer especially. While previous studies have discovered that the VDAC1 N-terminal helix is responsible for

Identification of VDAC1 as a cardioprotective target of Ginkgolide B

Chemico-Biological Interactions
Ginkgolide B (GB), a compound derived from Ginkgo biloba, exhibits significant cardioprotective properties, although its precise molecular target has yet to be identified. In this study, we synthesized a biotin-labeled GB probe (GB-biotin) to identify the molecular targets of GB.

Hypoxic VDAC1: A Potential Mitochondrial Marker for Cancer Therapy

2013
Finding new therapeutic targets to fight cancer is an ongoing quest. Because of insufficiencies in tumor vasculature, cells often are exposed to a hostile microenvironment that is low in oxygen (hypoxic) and nutrients. Thus, tumor cells face the challenge of finding new sources of energy and defying apoptosis, which allow them to survive, grow, and ...

Lipids influence the oligomeric organization of VDAC1

Biophysical Journal
The voltage-dependent anion channel (VDAC) is a mitochondrial outer membrane (MOM) β-barrel protein allowing passage of ions and metabolites (such as ATP, ADP, NADH⋯) in and out of the mitochondria. Besides its transport function, VDAC is implicated in mitochondrial regulation with roles in apoptosis, calcium homeostasis or neurodegeneration.
