4-hydroxynonenal
-
-
Ca2+
-
in presence of 1 mM Mg2+, slight activation up to 0.01 mM, significant inhibition above 0.1 mM
H2O2
-
H2O2 reversibly inhibits PTEN activity by covalently linking Cys-71 to Cys-124, inhibition partially reverses by inclusion of 100 mM dithiothreitol to the buffer
Laminin
-
laminin medium induces PTEN upregulation decreases transcription factor Sp1-binding activity
-
Mg2+
-
divalent cation required, maximal activition at 1 mM, inhibition above 1 mM
phosphatidylserine
-
0.2 mM, 75% loss of activity
reactive oxygen species
-
oxidation of the active site cysteine by reactive oxygen species inhibits PTEN
