Anti-Human MAPDA Polyclonal Antibody

N6-Methyl-AMP deaminase (MAPDA) is a ~40 kDa protein. Deaminase involved in the detoxification of modified adenosines containing N(6)-methylated adenine (m6A) post-transcriptional modification. Modified nucleosides are derived from the degradation of RNAs (mRNAs, rRNAs and tRNAs) and possess intrinsic cytotoxicity and must be cleared to prevent metabolic dysfunction. Acts downstream of ADK and catalyzes the hydrolysis of the free cytosolic methylated adenosine nucleotides N(6)-methyl-AMP (m6AMP), N(6),N(6)-dimethyl-AMP (m6,6AMP) and N(6)-isopentenyl-AMP (i6AMP) to produce inositol monophosphate (IMP). Catalyzes the removal of different alkyl groups not only from N6-substituted purine or 2-aminopurine nucleoside monophosphates but also from O6-substituted compounds in vitro.
