orphan date November 2007 Phosphatidylinositolphosphate kinases PIPK are kinase s that phosphorylate the phosphoinositide s PtdIns P and PtdIns P sub 2 sub that are derivatives of phosphatidylinositol PtdIns . It has been found that PtdIns is only phosphorylated on three 3,4,5 of its five hydroxyl groups, possibly because D 2 and D 6 hydroxyl groups cannot be phosphorylated because of steric hindrance ref Pettitt TR, Dove SK, Lubben A, Calaminus SDJ, Wakelam MJO.

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.

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.

Orphan date February 2009 merge organophosphates date February 2011 Alkyl phosphates belong to a group of organic compound s called organophosphorus compounds . They are ester s of phosphoric acid H sub 3 sub PO sub 4 sub and corresponding alcohol . For example, the formula of methyl phosphate is CH sub 3 sub H sub 2 sub PO sub 4 sub , dimethyl phosphate CH sub 3 sub sub 2 sub HPO sub 4 sub and trimethyl phosphate CH sub 3 sub sub 3 sub PO sub 4 sub . Alkyl phosphates are widely distributed in nature, and form the basis of most biological processes. For example, high energy metabolites such as Adenosine triphosphate ATP and Phosphoenolpyruvate PEP are alkyl phosphates, as are nucleic acids such as DNA and RNA . Alkyl phosphates are also important medicinally, for example the HIV drug Zidovudine AZT is inactive until it becomes an alkyl phosphate in vivo .
