ALKBH3 polyclonal antibody

ALKBH3 (alkB, alkylation repair homolog 3), also known as ABH3, PCA1 (prostate cancer antigen 1), DEPC1 or DEPC-1, is a 286 amino acid member of the AlkB family of proteins and functions as a dioxygenase with a preference for RNA and single stranded DNA substrates. ALKBH3 is one of many homologs of the Escherichia coli protein, AlkB. ALKBH3 is expressed in a wide variety of tissues and localizes to the cytoplasm and the nucleus. It associates with iron and 2-oxoglutarate, coupling the oxidation of substrates to the conversion of 2-oxoglutarate into succinate and CO2. Via oxidative demethylation, ALKBH3 repairs 1-methyladenine and 3-methylcytosine lesions in alkylated DNA and RNA. Its activity is stimulated by ascorbate. Two isoforms exist for ALKBH3 due to alternative splicing of the gene.
