APOBEC2 (Apolipoprotein B mRNA-editing enzyme catalytic subunit 2) is part of a family of enzymes that edit nucleic acids, possibly changing cytosine to uracil. APOBEC2 expression is regulated by TNF-α via NFκB activation and this suggests a possible role for APOBEC2 in the pathophysiology of hepatic inflammation. APOBEC2 has a low intrinsic cytidine deaminase activity and is also involved in DNA demethylation. APOBEC2 deaminates 5-methylcytosine, followed by base excision repair by Mbd4.
