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. Alternative splicing occurs for this gene, however, the full-length nature of all transcript variants has not yet been described. Source: Recombinant protein corresponding to aa1-441 from full length human IP6K1, fused to His-SUMO-Tag at N-terminal, expressed in E. coli.
