IMPA2 inositol monophosphatase 2 [Homo sapiens (human)] - Gene

Summary

Official Symbol: IMPA2provided by HGNC
Official Full Name: inositol monophosphatase 2provided by HGNC
Primary source: HGNC:HGNC:6051
See related: Ensembl:ENSG00000141401 MIM:605922; AllianceGenome:HGNC:6051
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Summary: This locus encodes an inositol monophosphatase. The encoded protein catalyzes the dephosphoylration of inositol monophosphate and plays an important role in phosphatidylinositol signaling. This locus may be associated with susceptibility to bipolar disorder. [provided by RefSeq, Jan 2011]
Expression: Broad expression in kidney (RPKM 73.3), skin (RPKM 38.8) and 18 other tissues See more

We conclude that miR-25-mediated IMPA2 downregulation constitutes a novel signature for cancer metastasis and poor outcomes in clear cell renal cell carcinoma (ccRCC). We further postulate that the therapeutic targeting of miR-25 can be useful for preventing the metastatic progression of ccRCC associated with IMPA2 downregulation.

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.
