Since specific residues from the positively charged motif at the PTEN N-terminus NLS (Lys13Arg14Arg15; KRR motif) (Fig 2A) are important for nuclear localization or phosphatase activity in vivo, we performed additional a

Evidence Type(s): Functional
Summary: Evidence Type: Functional | Mutation: K13R | Summary: The K13R mutation alters the nuclear localization of PTEN and enhances its ability to counteract PI3K activity in a yeast model. Evidence Type: Functional | Mutation: R14K | Summary: The R14K mutation affects the nuclear localization of PTEN and maintains its phosphatase activity in vivo. Evidence Type: Functional | Mutation: K13E | Summary: The K13E mutation results in a total loss of phosphatase activity in vivo. Evidence Type: Functional | Mutation: R15K | Summary: The R15K mutation increases the nuclear accumulation of PTEN but does not display phosphatase activity in vivo. Evidence Type: Functional | Mutation: K13A | Summary: The K13A mutation is part of a combined mutation that affects nuclear localization, indicating a role in PTEN's functional activity. Evidence Type: Functional | Mutation: R14A | Summary: The R14A mutation is part of a combined mutation that affects nuclear localization, indicating a role in PTEN's functional activity. Evidence Type: Functional | Mutation: R15A | Summary: The R15A mutation is part of a combined mutation that affects nuclear localization, indicating a role in PTEN's functional activity.
