Protein
Protein phosphatase Slingshot homolog 1
Gene
Ssh1, Kiaa1298, Ssh1l
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Protein phosphatase which regulates actin filament dynamics. Dephosphorylates and activates the actin binding/depolymerizing factor cofilin, which subsequently binds to actin filaments and stimulates their disassembly. Inhibitory phosphorylation of cofilin is mediated by LIMK1, which may also be dephosphorylated and inactivated by this protein.1 Publication

Catalytic activityi

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.
[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.

Post-translational modificationi

Phosphorylated. Inhibitory phosphorylation by PAK4 promotes binding to YWHAZ. Phosphorylation at Ser-970 is decreased by stimuli which promote actin reorganization and lamellipodia formation. Can be dephosphorylated and activated by PPP3CA/calcineurin A. Phosphorylation decreases immediately prior to telophase By similarity.
