Phosphatidylinositol 5 phosphate PtdIns5P or PI5P is one of the seven Phosphatidylinositol phosphoinositides , and is the last to have been discovered to be naturally occurring. In 1997 Lucia Rameh, while working as a postdoctoral fellow with Lewis C. Cantley observed that the enzymes referred to as type II PIP kinases did not utilize PtdIns4P as a substrate as had been proposed . In fact, they required PtdIns5P as a substrate to produce PtdIns 4,5 P2. The observation immediately suggested that cells must contain a natural pool of PtdIns 5 P, a prediction that was verified by Rameh, Cantley, and colleagues. ref name Rameh cite journal author Rameh LE, Tolias KF, Duckworth BC, Cantley LC title A new pathway for synthesis of phosphatidylinositol 4,5 bisphosphate journal Nature volume 390 issue 6656 pages 192 6 year 1997 month November pmid 9367159 doi 10.1038 36621 url ref The function of PtdIns5P remains uncertain, especially since no specific PtdIns5P binding proteins have been unambiguously identified.

It is the product of both the class II and III phosphoinositide 3 kinases PI 3 kinases activity on phosphatidylinositol . PtdIns3 P is dephophosphorylated by the myotubularin family of phosphatase s, on the D3 position of the inositol ring, and can be converted to Phosphatidylinositol 3,5 bisphosphate PtdIns 3,5 P sub 2 sub by the lipid kinase PIKFYVE PIKfyve . Both FYVE domains and PX domain s &ndash found in proteins such as SNX1 , Hrs , and EEA1 &ndash bind to PtdIns3 P . The majority of PtdIns3 P appears to be constitutively synthesised by the class III PI 3 kinase , Vps34, at endocytic membranes. Class II PI 3 kinases also appear to synthesise PtdIns3 P , their activity however appears to be regulated by a range of stimuli, including growth factors. This suggests that specific pools of PtdIns3 P may be synthesised upon cell stimulation.
