Dual specificity protein phosphatase PHS1 (IPR035010)

Short name: PHS1

Overlapping homologous superfamilies


Family relationships


PHS1 is dual-specificity phophosphatase from plants. It specifically interacts with two MAPKs, MPK12 and MPK18. PHS1-MPK18 signalling probably regulates cortical microtubule functions [PMID: 19392697, PMID: 15208393]. It is also a negative regulator of abscisic acid (ABA) signalling [PMID: 16889651]. Plant hormone ABA control numeros processes, such as dormancy and germination of seeds, senescence and resistance to abiotic stresses.
