Summary: Enables phosphatidylinositol-3,4,5-trisphosphate 3-phosphatase activity and protein serine/threonine phosphatase activity. Involved in several processes, including negative regulation of hemocyte differentiation; negative regulation of signal transduction; and regulation of neuron projection development. Located in endosome membrane. Is expressed in adult head; embryonic/larval salivary gland; embryonic/larval salivary gland body; medullary zone of lymph gland primary lobe; and organism. Used to study cancer and disease of metabolism. Human ortholog(s) of this gene implicated in several diseases, including PTEN hamartoma tumor syndrome (multiple); breast cancer (multiple); liver disease (multiple); nervous system cancer (multiple); and reproductive organ cancer (multiple). Orthologous to human PTEN (phosphatase and tensin homolog). [provided by Alliance of Genome Resources, Dec 2024]

Roles of PINK1 in regulation of systemic growth inhibition induced by mutations of PTEN in Drosophila.
Title: Roles of PINK1 in regulation of systemic growth inhibition induced by mutations of PTEN in Drosophila.
Our findings identify a novel PTEN/dPLCXD pathway that controls PtdIns(4,5)P2 levels on endosomes. They also point to a potential new strategy for the treatment of Lowe syndrome.
Title: PTEN reduces endosomal PtdIns(4,5)P(2) in a phosphatase-independent manner via a PLC pathway.
Here we show that PTEN mutation impacts aPKC and Lgl protein levels also in Drosophila. Moreover, we demonstrate that PI3K activation is not sufficient to trigger tumourigenesis, while aPKC promotes hyperplastic growth of the neuroepithelium and a noticeable expansion of the type II neuroblasts.
Title: Failure of the PTEN/aPKC/Lgl Axis Primes Formation of Adult Brain Tumours in Drosophila.
Ectopic expression of dPTEN (a phosphatase and tensin homologue) in the fat body prolongs fruit fly life.
Title: Basic mechanisms of longevity: A case study of Drosophila pro-longevity genes.
PTEN deficient cells proliferate under conditions of nutrient restriction.
Title: Nutrient restriction enhances the proliferative potential of cells lacking the tumor suppressor PTEN in mitotic tissues.
loss of the tumor suppressor PTEN disrupts cell rearrangements by preventing the lengthening of newly formed junctions that become unstable and keep on rearranging
Title: PTEN controls junction lengthening and stability during cell rearrangement in epithelial tissue.
study demonstrates that in the Drosophila lymph gland the tumor suppressors TSC and PTEN control blood progenitor proliferation through a common TOR- and 4EBP-dependent pathway
Title: Multifaceted roles of PTEN and TSC orchestrate growth and differentiation of Drosophila blood progenitors.
Regeneration of Drosophila sensory neuron axons and dendrites is regulated by the Akt pathway involving Pten and microRNA bantam.
Title: Regeneration of Drosophila sensory neuron axons and dendrites is regulated by the Akt pathway involving Pten and microRNA bantam.
Loss of the tumor suppressor Pten promotes proliferation of Drosophila melanogaster cells.
Title: Loss of the tumor suppressor Pten promotes proliferation of Drosophila melanogaster cells in vitro and gives rise to continuous cell lines.
A mutation in the pleckstrin homology (PH) domain of Akt that reduces its affinity for PIP3 sufficed to rescue the lethality of flies devoid of PTEN activity.
Title: Living with lethal PIP3 levels: viability of flies lacking PTEN restored by a PH domain mutation in Akt/PKB.
