    Summary
    Predicted to enable inorganic diphosphate phosphatase activity and protein serine/threonine phosphatase activity. Predicted to be involved in diphosphate metabolic process; phosphate-containing compound metabolic process; and regulation of mitochondrial membrane potential. Predicted to be active in mitochondrion and synapse. Orthologous to human PPA2 (inorganic pyrophosphatase 2). [provided by Alliance of Genome Resources, Nov 2024]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
