Summary: This gene encodes a member of the inositol phosphokinase family. The encoded protein has 3-kinase, 5-kinase and 6-kinase activities on phosphorylated inositol substrates. The encoded protein plays an important role in the biosynthesis of inositol 1,3,4,5,6-pentakisphosphate, and has a preferred 5-kinase activity. This gene may play a role in nuclear mRNA export. Pseudogenes of this gene are located on the long arm of chromosome 13 and the short arm of chromosome 19. [provided by RefSeq, Dec 2010]

Data suggest that IPMK exhibits constrained, horseshoe-shaped substrate pocket, formed from an alpha-helix, a 3(10) helix, and a recently evolved tri-proline loop; headgroups of substrates (inositol 4,5-bisphosphate and inositol 1,4,5-trisphosphate) bind in precisely the same orientation, indicative of evolutionary optimization of 3-kinase activities against both substrates.

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.
