Protein Information (annotations from UniProt)

Database IDHIV0002171
UniProt IDQ6ZVD8
Primary gene name(s)PHLPP2
Synonym gene name(s)KIAA0931, PHLPPL
Protein namePH domain leucine-rich repeat-containing protein phosphatase 2
Protein functionProtein 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 AKT1, 'Ser-660' of PRKCB isoform beta-II and 'Ser-657' of PRKCA. 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 decreases cell proliferation. Also controls the phosphorylation of AKT3. 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. Dephosphorylation of PRKCA and PRKCB leads to their destabilization and degradation. Dephosphorylates RAF1 inhibiting its kinase activity, PubMed:24530606. {ECO:0000269|PubMed:17386267, ECO:0000269|PubMed:18162466, ECO:0000269|PubMed:19079341, ECO:0000269|PubMed:20513427, ECO:0000269|PubMed:21986499, ECO:0000269|PubMed:24530606}.
