The function of MPND (MPN domain containing, ENSG00000008382) is as follows. Probable protease (By similarity). Acts as a sensor of N(6)- methyladenosine methylation on DNA (m6A): recognizes and binds m6A DNA, leading to its degradation (PubMed:30982744). Binds only double strand DNA (dsDNA) in a sequence-independent manner (By similarity). {ECO:0000250|UniProtKB:Q3TV65, ECO:0000250|UniProtKB:Q5VVJ2, ECO:0000269|PubMed:30982744}.
