Protocol Available protocols: Western Blotting, Immunohistochemistry (Paraffin) Specificity / Sensitivity AHCY/SAHH (F2O1K) Rabbit Monoclonal Antibody recognizes endogenous levels of total AHCY/SAHH protein. Species Reactivity: Human, Mouse, Rat Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human AHCY/SAHH protein. Background Adenosylhomocysteinase (AHCY), also known as S-adenosyl-L-homocysteine hydrolase (SAHH), catalyzes the hydrolysis of SAH to generate homocysteine and adenosine (1,2). SAH is a by-product in the transmethylation reactions catalyzed by S-adenosylmethionine (SAM)-dependent methyltransferases. These methylation reactions are critical to various biological processes. SAH is also a feedback inhibitor of SAM-dependent methyltransferases. By catalyzing the above reaction, AHCY/SAHH plays a crucial role in relieving the inhibition (3). Moreover, studies show that hydrogen sulfide (H S) persulfidates Cys195 on AHCY/SAHH in human non-small cell lung cancer (NSCLC) cells and therefore decreases its enzymatic activity, resulting in reduced homocysteine levels. This, in turn, lowers cysteine and glutathione levels in the cell when cystine is depleted, making NSCLC cells more susceptible to ferroptosis (2,4).
