Protein Kinase Classification: AGC/MAST※ MAST family introduction MASTs (Microtubule-associated Serine/Threonine-protein kinases) belong to AGC group. The MAST kinases are characterized by the presence of a Serine/Threonine kinase domain, a second 3' MAST domain and PDZ domain. The PDZ domain has been reported to mediate interaction with others proteins and help MAST to facilitate functionally important phosphorylation. The N-terminal kinase catalytic domain is relatively conserved in MAST family with a high identity (>60%). MAST family is expressed in multiple tissues. In nervous system, MAST may act as a key role through localization within the DAPC/UAPC, which is found within region of the neuromuscular junction (NMJ) and central synapses (1). Recently gene rearrangements involving MAST and Notch have been reported. Overexpression of MAST1 or MAST2 gene fusions plays an important effect on proliferative (2).
