IP6K1 (Inositol Hexakisphosphate Kinase 1) is a Protein Coding gene. Among its related pathways are Metabolism and Inositol phosphate metabolism (KEGG). IP6K1 encodes a member of the inositol phosphokinase family. The encoded protein may be 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. Alternatively spliced transcript variants have been described.
