Anti-Adenine Nucleotide Translocase Immunocapture antibody [5F51BB5AG7] (ab109864)

Relevance

ANT is a reversible transporter of ATP and ADP. During oxidative phosphorylation (OXPHOS) the protein exchanges ATP out for ADP in, however, in the absence of OXPHOS ANT works in reverse to maintain mitochondrial membrane potential. A subset of patients with heart related diseases have been shown to harbor mutations in the ANT gene or to develop an autoimmune reaction against the protein. There are a number of proteins found in mitochondria that, under circumstances favoring apoptosis, coalesce to form the so-called permeability transition pore. The proteins identified as a part of the PTP include cytosolic hexokinase, outer membrane porin (also called the voltage dependent anion channel or VDAC), adenylate cyclase in the intermembrane space, the adenine nucleotide transporter (ANT) and the peripheral benzodiazepine receptor protein of the inner membrane along with cyclophilin D of the matrix space. Hexokinase, porin and ANT all occur as isoforms and it remains to be determined whether there is specificity of these different forms for the PTP.
