• Beschreibung

  D-myo-Inositol-1,4,5,6-tetraphosphate (sodium salt) (Ins(1,4,5,6)-P₄) is one of several different inositol oligophosphate isomers implicated in signal transduction. Production of Ins(1,4,5,6)-P₄ by intestinal epithelial cells increases approximately 2-14 fold, depending on the strain and incubation time, following infection with Salmonella.¹ Ins(1,4,5,6)-P₄ antagonizes epidermal growth factor (EGF) signalling through the phosphatidylinositol 3-kinase pathway.¹ Ins(1,4,5,6)-P₄ (tested as the D/L racemic mixture) is ~1,000-fold less potent than Ins(1,4,5)-P₃ at initiating Ca²⁺ release when injected into Xenopus oocytes.²
