Summary
Enables protein serine/threonine phosphatase activity. Predicted to be involved in diphosphate metabolic process; phosphate-containing compound metabolic process; and regulation of mitochondrial membrane potential. Located in mitochondrion. Is active in synapse. Orthologous to human PPA2 (inorganic pyrophosphatase 2). [provided by Alliance of Genome Resources, Nov 2024]
Expression
Ubiquitous expression in adrenal adult (RPKM 80.8), kidney adult (RPKM 69.5) and 28 other tissues See more

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.
