Biochimie. Korean Diabetes Journal, 2010. eCollection 2020. Adenine nucleotide translocase (ANT) mediates the exchange of ADP and ATP on the inner mitochondrial membrane in healthy cells. In addition to its normal function, the adenine nucleotide translocase (ANT) forms the inner membrane channel of the mitochondrial permeability transition pore (MPTP). Molecular modeling of the loop containing the ADP binding site suggests an arrangement of aspartate and glutamate residues that may provide a calcium binding site. Toxicol In Vitro. ANT-1 is a component of the mitochondrial permeability transition complex, a protein aggregate connecting the inner with the outer mitochondrial membrane that has recently been implicated in apoptosis. The mitochondrial phosphate carrier interacts with cyclophilin D and may play a key role in the permeability transition. Upon that revelation, the researchers designed tests to investigate whether mutations in the genes of ANT affected mitophagy. GeneCards - The Human Gene Compendium We investigated whether ANT1 overexpression has … Korotkov SM, Konovalova SA, Brailovskaya IV, Saris NE.

Mitochondrial protein-lysine N-methyltransferase that trimethylates adenine nucleotide translocases ANT2/SLC25A5 and ANT3/SLC25A6, thereby regulating mitochondrial respiration (PubMed:31213526). This process, called oxidative phosphorylation, converts adenosine diphosphate (ADP) into adenosine triphosphate (ATP), the cell's main energy source. Abstract: In addition to its normal function, the adenine nucleotide translocase (ANT) forms the inner membrane channel of the mitochondrial permeability transition pore (MPTP). Adenine nucleotide translocator (ANT), also known as the ADP/ATP translocase(ANT), ADP/ATP carrier protein (AAC) or mitochondrial ADP/ATP carrier, exchanges free ATP with free ADP across the inner mitochondrial membrane. adenine nucleotide translocase.

2016 Apr;32:320-32. doi: 10.1016/j.tiv.2016.01.015. Epub 2008 Jul 30. ANT is the transporter protein that shuttles ADP and ATP across the inner mitochondrial membrane, enabling the energy released from catabolism to be made available to the rest of the cell. Neil Benn, Managing Director at Ziath Ltd. Binding of cyclophilin-D (CyPD) to its matrix surface (probably on Pro61 on loop 1) facilitates a calcium-triggered conformational change converting it from a specific transporter to a non-specific pore. The exchange of ADP and ATP across the inner mitochondrial membrane is a fundamental cellular process. Adenine nucleotide translocase (ANT), a mitochondrial ADP/ATP transporter, was protective against CS in Dictyostelium and human bronchial epithelial cells. Adenine nucleotide translocase (ANT) mediates the exchange of ADP and ATP on the inner mitochondrial membrane in healthy cells. 31. After the consequent hydrolysisof ATP into ADP, ADP is transported back into the mitochondrial matrix, where it can be rephosphorylated to ATP. ADP/ATP translocase transports ATP synthesized from oxidative phosphorylation into the cytoplasm, where it can be used as the principal energy currency of the cell to power thermodynamically unfavorable reactions. Thus the ANT may provide a molecular link between physiopathological mechanisms of infection and the regulation of MPTP function and so represents a potential therapeutic target. Complete information for ANTKMT gene (Protein Coding), Adenine Nucleotide Translocase Lysine Methyltransferase, including: function, proteins, disorders, pathways, orthologs, and expression. Obrador E, Salvador R, López-Blanch R, Jihad-Jebbar A, Vallés SL, Estrela JM. In revealing the link between ANT and mitophagy, and the impact mutations have on quality control, our findings change the way we think about the disease-causing mutations and enable us to focus our attention on the right pathway. The SLC25A4 gene provides the instructions for making a protein called adenine nucleotide translocase type 1 (ANT1). Mitochondria play key roles in energy production and intracellular reactive oxygen species (ROS) generation. To their surprise, they found that ANT is required for the quality control pathway of mitophagy in a number of cell types. Gene Function. Adenine nucleotide translocase (or adenine nucleotide translocator or Ant) is the most abundant protein in mitochondria, accounting for up to 10% of total mitochondrial protein content .

Epub 2020 May 23. COVID-19 is an emerging, rapidly evolving situation. Now, researchers at Penn Medicine discovered that ANT is critical for a quality control process called mitophagy-;which helps to ensure the integrity of the mitochondria network by removing damaged mitochondria-;and found that mutations that lead to a defective quality control system ultimately cause heart disease. The Ca2+-modified adenine nucleotide translocase (ANT) and F 0F1 ATP synthase are the major contenders for the role of pore in the PTP. In addition, ANT can … Add Adenine Nucleotide Translocator to your PopFlock.com topic list or share. Owned and operated by AZoNetwork, © 2000-2021. This provides helpful insights into MPTP regulation by adenine nucleotides, membrane potential and ANT ligands such as carboxyatractyloside and bongkrekic acid. Probably also trimethylates ANT1/SLC25A4 (PubMed:31213526). Kim HS, Je JH, Son TG, Park HR, Ji ST, Pokharel YR, et al. 31. Here, we describe the isolation of adenine nucleotide translocase-1 (ANT-1) in a screen for dominant, apoptosis-inducing genes. A mitochondrial membrane complex consisting of ATP synthase, adenine nucleotide translocase (ATP-ADP translocase), and phosphate translocase functions in oxidative phosphorylation. ANT1 functions in mitochondria, which are structures within cells that convert the energy from food into a form that cells can use. A 20/20 view of ANT function in mitochondrial biology and necrotic cell death. It is encoded by the nuclear DNA, synthesized in cytosol, imported into mitochondria, and finally inserted into the inner membrane [ 9 – 11 ]. HHS NX_Q9BQD7 - ANTKMT - Adenine nucleotide translocase lysine N-methyltransferase - Function. These included members of the Bax/Bcl-2 family (both oncoproteins and tumor suppressors) and viral proteins. The age-related elevation in ANT carbonyl content was correlated with a corresponding loss in its functional activity. Zoltan Arany, MD, PhD, the study's corresponding author and a professor of Cardiovascular Medicine in the Perelman School of Medicine at the University of Pennsylvania.
