Gene Ontology Information

Protein Name	Vip1p
Description	Bifunctional inositol pyrophosphate kinase and phosphatase; contains an N-terminal PP-InsP kinase domain that phosphorylates inositol hexakisphosphate and heptakisphosphate, and a C-terminal phosphatase domain that hydrolyzes both 1PP-InsP5 and 5PP-InsP5; IP7 levels decrease during starvation, suggesting a role for PP-InsP enzymes in Pi homeostasis; may regulate the dimorphic switch and the function of the cortical actin cytoskeleton
GO Terms: Biological Process	level 5: inositol metabolic process level 6: phosphorylation level 6: inositol phosphate biosynthetic process
GO Terms: Molecular Function	level 3: transferase activity level 4: nucleotide binding level 5: kinase activity level 6: ATP binding level 6: 5-diphosphoinositol pentakisphosphate 3-kinase activity level 6: inositol-1,3,4,5,6-pentakisphosphate kinase activity level 6: inositol hexakisphosphate kinase activity level 6: inositol heptakisphosphate kinase activity level 6: diphosphoinositol-pentakisphosphate kinase activity level 7: inositol hexakisphosphate 1-kinase activity level 7: inositol hexakisphosphate 3-kinase activity level 7: inositol hexakisphosphate 4-kinase activity level 7: inositol hexakisphosphate 6-kinase activity level 7: inositol hexakisphosphate 5-kinase activity level 8: inositol-5-diphosphate-1,2,3,4,6-pentakisphosphate diphosphatase activity level 8: inositol 1-diphosphate 2,3,4,5,6-pentakisphosphate 1-diphosphatase activity
