About IP6K2

Cytogenetic location: 3p21.31 Genomic coordinates (GRCh38): 3:48,688,003-48,717,221 (from NCBI)

This gene has 28 transcripts (splice variants), 267 orthologues and 6 paralogues. Ubiquitous expression in bone marrow (RPKM 16.6), skin (RPKM 16.3) and 25 other tissues.

Summary

This gene encodes a protein that belongs to the inositol phosphokinase (IPK) family. This protein is likely responsible for the conversion of inositol hexakisphosphate (InsP6) to diphosphoinositol pentakisphosphate (InsP7/PP-InsP5). It may also convert 1,3,4,5,6-pentakisphosphate (InsP5) to PP-InsP4 and affect the growth suppressive and apoptotic activities of interferon-beta in some ovarian cancers. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]
