Summary
Enables inositol-polyphosphate 5-phosphatase activity; phosphatidylinositol monophosphate phosphatase activity; and protein domain specific binding activity. Involved in inositol phosphate catabolic process and phosphatidylinositol dephosphorylation. Located in axon terminus; cytoplasmic microtubule; and ruffle membrane. Is active in presynapse. Orthologous to human SYNJ2 (synaptojanin 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.
