IUBMB Comments

Requires Mg2+. Peptide array data suggest that MASTL prefers to phosphorylate Ser over Thr, followed at position +1 by a bulky hydrophobic (Met, Leu, Phe or Tyr) and with an aromatic residue in the -2 position . Its main role in animal systems is in the regulation of mitosis by phosphorylating a conserved site on endosulfine family proteins (ENSA and ARPP-19 in human), causing them to inhibit the protein phosphatase 2A-B55 [protein phosphatase 2A (PP2A) holoenzyme complex containing a B55-family regulatory subunit] .
