Phosphatase Subfamily PPM1E
From PhosphataseWiki
Phosphatase Classification: Superfamily PPM (PP2C): Family PPM (PP2C): Subfamily PPM1E
The subfamily is named named after two human PPMs, PPM1E (also known as POXP1, PP2CH, caMKN, CaMKP-N) and PPM1F (also known as POXP2, CAMKP, FEM-2, hFEM-2, CaMKPase). The subfamily has a single copy in most non-vertebrates from Monosiga to ciona, and duplicated when vertebrates emerged. Both PPM1E and PPM1F dephosphorylate kinases CaMK2g and PAK, and PPM1E can also dephosphorylate CaMK4 (of different families from CaMK2g).
The subfamily has some potent inhibitors [1].
