※ aDSP family introduction

    aDSP (Atypical DSP) family contains phosphatases which are poorly characterized, they are smaller than MKP family and lack specific MAP kinase motifs (1). Family member DUSP3 is invloved in down-regulating the ERK pathway and specifically dephosphorylates and inactivates ERK1 and ERK2 (2). DUSP11 show phosphatase activity towards RNA 5'-triphosphatase and may participate in nuclear mrna metabolism. The studies show that most of aDSP phosphatase have function unrelated to MAP kinases (3).
