Identification
NamePhosphatidylinositol 4-kinase PIK1
Synonyms
  • PI4-kinase
  • PtdIns-4-kinase
Gene NamePIK1
Enzyme Class
Biological Properties
General FunctionInvolved in binding
Specific FunctionActs on phosphatidylinositol (PI) in the first committed step in the production of the second messenger inositol-1,4,5,- trisphosphate. PIK1 is part of a nuclear phosphoinositide cycle and could control cytokinesis through the actin cytoskeleton
