The deduced 227-amino acid protein has a calculated molecular mass of 25.6 kD. AK3 shares 57.4% amino acid identity with AK4 (AK3L1). It shares 75%, 90%, and 91% amino acid identity with bovine, rat, and mouse Ak3, respectively. Northern blot analysis detected a 3.2-kb transcript in all tissues examined. Expression was highest in heart, liver, and skeletal muscle, moderate in kidney and pancreas, and weak in brain, placenta, and lung. Transcripts of 5, 1.8, and 1.35 kb were detected in heart, liver, and pancreas. Western blot analysis detected AK3 at an apparent molecular mass of 28 kD in all tissues examined. Subcellular fractionation of mouse liver and kidney detected Ak3 in the mitochondrial fraction.Human embryonic kidney cells had endogenous phosphotransferase activity, which increased following transfection of AK3 cDNA.
Human GTP:AMP phosphotransferase, mitochondrial (AK3) ELISA Kit employs a two-site sandwich ELISA to quantitate AK3 in samples. An antibody specific for AK3 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyAK3 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for AK3 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of AK3 bound in the initial step. The color development is stopped and the intensity of the color is measured.
