Serine/threonine/tyrosine-interacting-like protein 1 (STYXL1)

Catalytically inactive phosphatase (PubMed:20180778, PubMed:23163895). By binding to G3BP1, inhibits the creation of G3BP1-induced stress granules (PubMed:20180778, PubMed:23163895).

Doesn't act by protecting the dephosphorylation of G3BP1 in'Ser- 149' (PubMed:23163895). Inhibits PTPMT1 phosphatase activity (PubMed:24709986).
