calcium-mediated signaling phosphatidylinositol 3-kinase/protein kinase B signal transduction obsolete inositol phosphate-mediated signaling https://github.com/geneontology/go-ontology/issues/25718 true inositol phosphate-mediated signalling OBSOLETE. A intracellular signal transduction in which the signal is transmitted within the cell via an inositol phosphate. Includes production of the inositol phosphate, and downstream effectors that further transmit the signal within the cell. Inositol phosphates are a group of mono- to poly-phosphorylated inositols, and include inositol monophosphate (IP), inositol trisphosphate (IP3), inositol pentakisphosphate (IP5) and inositol hexaphosphate (IP6). GO:0048016 This term was obsoleted because it was not clearly defined and represented several pathways in which the level of some inositol phosphate level was altered. biological_process
