Bis(5'-nucleosyl)-tetraphosphatase [asymmetrical] is an enzyme that in humans is encoded by the NUDT2 gene.{{cite journal | vauthors = Thorne NM, Hankin S, Wilkinson MC, Nunez C, Barraclough R, McLennan AG | title = Human diadenosine 5',5"'-P1,P4-tetraphosphate pyrophosphohydrolase is a member of the MutT family of nucleotide pyrophosphatases | journal = Biochem J | volume = 311 | issue = 3| pages = 717–21 |date=Dec 1995 | pmid = 7487923 | pmc = 1136061 | doi = 10.1042/bj3110717}}{{cite journal | vauthors = McLennan AG, Flannery AV, Morten JE, Ridanpaa M | title = Chromosomal localization of the human diadenosine 5',5"'-P1,P4-tetraphosphate pyrophosphohydrolase (Ap4A hydrolase) gene (APAH1) to 9p13 | journal = Genomics | volume = 47 | issue = 2 | pages = 307–9 |date=Apr 1998 | pmid = 9479504 | doi = 10.1006/geno.1997.5092 }}{{cite web | title = Entrez Gene: NUDT2 nudix (nucleoside diphosphate linked moiety X)-type motif 2| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=318}}
This gene encodes a member of the MutT family of nucleotide pyrophosphatases, a subset of the larger NUDIX hydrolase family. The gene product possesses a modification of the MutT sequence motif found in certain nucleotide pyrophosphatases. The enzyme asymmetrically hydrolyzes Ap4A to yield AMP and ATP and is responsible for maintaining the intracellular level of the dinucleotide Ap4A, the function of which has yet to be established. This gene may be a candidate tumor suppressor gene. Alternative splicing has been observed at this locus and three transcript variants, all encoding the same protein, have been identified.
