These enzymes can also remove the 5-phosphate from Ins(1,4,5)P3 and/or Ins(1,3,4,5)P4. They are a diverse family of enzymes, with differing abilities to catalyse two or more of the four reactions listed. They are thought to use inositol lipids rather than inositol phosphates as substrates in vivo. All of them can use either or both of PtdIns(4,5)P2 and PtdIns(3,4,5)P3 as substrates; this is the main property that distinguishes them from EC 3.1.3.56, inositol-polyphosphate 5-phosphatase.

expression of 5PTase13 is suppressed by blue light irradiation. Expression level of 5PTase13 is significantly enhanced in phototropin1 single or phototropin1 phototropin2 double mutants under blue light

nonredundant function of At5PTase7 in salt stress response by regulating ROS production and gene expression, involvement of the At5PTases in Arabidopsis salt tolerance, overview
mutant sac9-1 plants have a constitutively stressed phenotype with shorter roots which notably accumulate phosphatidylinositol 4,5-bisphosphate and its hydrolysis product inositol trisphosphate, phenotype with extreme abnormalities of cell wall and membrane structures in sac9-1 primary root cells, regardless of cell type, position within the meristematic area, and plane of section, overview

disruption of the gene 5PTase13 results in shortened hypocotyls and expanded cotyledons. Suppression of 5PTase13 expression rescues the elongated hypocotyls in the phototropin1 or phototropin1 phototropin2 mutants. Further analysis shows that the blue light-induced elevation of cytosolic Ca2+ is inhibited in the phot1 mutant but enhanced in the 5pt13 mutant, suggesting that 5PTase13 antagonizes phototropin1-mediated effects on calcium signaling under blue light

random mutagensis and identification of mutant At5ptase7, that shows increased sensitivity, which is improved by overexpression. At5ptase7 mutants demonstrate reduced production of reactive oxygen species, phenotype, overview. Supplementation of mutants with exogenous PtdIns dephosphorylated at the D5' position restores ROS production, while PtdIns(4,5)P2, PtdIns(3,5)P2, or PtdIns(3,4,5)P3 are ineffective
