Scientific Data Images for Human Adenosylhomocysteinase/AHCY Antibody

Detection of Human Adenosylhomocysteinase/AHCY antibody by Western Blot.

Detection of Human Adenosylhomocysteinase/AHCY by Western Blot.

Western blot shows lysates of Bowes human melanoma cell line and HeLa human cervical epithelial carcinoma cell line. PVDF Membrane was probed with 1 µg/mL of Human Adenosylhomocysteinase/AHCY Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6466) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (HAF016). A specific band was detected for Adenosylhomocysteinase/AHCY at approximately 48 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Detection of Human Adenosylhomocysteinase/AHCY by Simple WesternTM.

Simple Western shows lysates of Exosome Standards (HT‑29) (NBP3-11685), Exosome Standards (PC‑3) (NBP2-49856) and K562 human chronic myelogenous leukemia cell line, loaded at 0.5 mg/ml. A specific band was detected for Adenosylhomocysteinase/AHCY at approximately 50 kDa (as indicated) using 10 µg/mL of Sheep Anti-Human Adenosylhomocysteinase/AHCY Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6466). This experiment was conducted under reducing conditions and using the 12-230kDa separation system.

Background: Adenosylhomocysteinase/AHCY

Human S‑Adenosylhomocysteinase (AHCY) is a cytoplasmic tetramer with a tightly bound NAD co‑factor for each subunit (1, 2). It is the only known enzyme to catalyze the breakdown of S‑adenosylhomocysteine (AdoHcy) to homocysteine and adenosine. AdoHcy hydrolysis is a reversible reaction with an equilibrium favoring AdoHcy formation, but hydrolysis prevails under physiological conditions due to the rapid removal of adenosine and homocysteine. Thus, AHCY’s activity in mammals is directly related to homocysteine level, an independent risk factor for vascular disease (3). It also functions as a regulator of biological transmethylation by controlling the concentration of AdoHcy, a potent competitive inhibitor of all S‑adonosyl-L-methionine methyltransferases (1). A mutation in the human AHCY results in AHCY deficiency with increase of plasma creatine kinase, methionine, S‑adenosylmethionine and AdoHcy, delay of myelination, myopathy and psychomotor retardation (4, 5).
