| Tchem | PH domain leucine-rich repeat-containing protein phosphatase 1 |
Protein phosphatase involved in regulation of Akt and PKC signaling. Mediates dephosphorylation in the C-terminal domain hydrophobic motif of members of the AGC Ser/Thr protein kinase family; specifically acts on 'Ser-473' of AKT2 and AKT3, 'Ser-660' of PRKCB and 'Ser-657' of PRKCA (PubMed:15808505, PubMed:17386267, PubMed:18162466). Isoform 2 seems to have a major role in regulating Akt signaling in hippocampal neurons (By similarity). Akt regulates the balance between cell survival and apoptosis through a cascade that primarily alters the function of transcription factors that regulate pro- and antiapoptotic genes. Dephosphorylation of 'Ser-473' of Akt triggers apoptosis and suppression of tumor growth. Dephosphorylation of PRKCA and PRKCB leads to their destabilization and degradation (PubMed:18162466). Dephosphorylates STK4 on 'Thr-387' leading to STK4 activation and apoptosis (PubMed:20513427). Dephosphorylates RPS6KB1 and is involved in regulation of cap-dependent translation (PubMed:21986499). Inhibits cancer cell proliferation and may act as a tumor suppressor (PubMed:19079341). Dephosphorylates RAF1 inhibiting its kinase activity (PubMed:24530606). May act as a negative regulator of K-Ras signaling in membrane rafts (By similarity). Involved in the hippocampus-dependent long-term memory formation (By similarity). Involved in circadian control by regulating the consolidation of circadian periodicity after resetting (By similarity). Involved in development and function of regulatory T-cells (By similarity).
This gene encodes a member of the serine/threonine phosphatase family. The encoded protein promotes apoptosis by dephosphorylating and inactivating the serine/threonine kinase Akt, and functions as a tumor suppressor in multiple types of cancer. Increased expression of this gene may also play a role in obesity and type 2 diabetes by interfering with Akt-mediated insulin signaling. [provided by RefSeq, Dec 2011]

| 26823799 | our results suggest that PHLPP1 plays a crucial role in sacral chordoma |
| 26463718 | high levels of PHLPP might reflect a less aggressive lung adenocarcinoma phenotype and predict better survival in patients with lung adenocarcinoma. |
| 26427440 | Data show that both serine/threonine phosphatases PHLPP and dephosphorylated the physiological substrates of Akt1 and Akt3 with similar efficiencies. |
| 26245343 | Results showed that PHLPP1 and PHLPP2 gene expression are down-regulated in esophageal squamous cell carcinoma. Their promotor is a target for mir-224. |
| 25793736 | Aberrant expression of PHLPP1 and PHLPP2 correlates with poor prognosis in patients with hypopharyngeal squamous cell carcinoma |
| 25776496 | PHLPP1, along with miR-522, promoted tumor cell growth in glioblastoma cells. |
| 24945731 | miR-141 and its targets PHLPP1 and PHLPP2 play critical roles in NSCLC tumorigenesis |
| 24892992 | biochemical characterization of phosphatase domain of PHLPP1 and PHLPP2;PHLPP1 and PHLPP2 have similar in vitro activities and respond comparably to the presence of metallic ions; metallic ions affect structural stability of the domain;identified 3 residues likely involved in metal coordination and 2 that may be important for structural integrity |
| 24599953 | conclude that cross-talk between PTEN and PHLPPs is silenced in normal prostate cells but activated in TGF-beta1 transformed prostate stem and cancer cells and facilitates invasive growth |
| 24393845 | PHLPP1 is a binding protein for Mst1 and it modulates the Hippo pathway by dephosphorylating Mst1 at the inhibitory Thr(387) of Mst1. |
