SET7/9 is a protein lysine methyltransferase that methylates histone H3 and nonhistone proteins such as p53, TAF10 and oestrogen receptor α. In previous work, novel inhibitors of SET7/9 that are amine analogues of the coenzyme S-(5'-adenosyl)-L-methionine (AdoMet) have been developed. Here, crystal structures of SET7/9 are reported in complexes with two(More)
The vacuolar-type H+-ATPase (V-ATPase) is a multi-subunit proton pump that is involved in both intra- and extracellular acidification processes throughout human body. Subunits constituting the peripheral stalk of the V-ATPase are known to have several isoforms responsible for tissue/cell specific different physiological roles. To study the different(More)
Ribosomal protein S6 kinase 1 (S6K1) is a serine/threonine protein kinase that plays an important role in the PIK3/mTOR signaling pathway, and is implicated in diseases including diabetes, obesity, and cancer. The crystal structures of the S6K1 kinase domain in complexes with staurosporine and the S6K1-specific inhibitor PF-4708671 have been reported. In(More)
The small kinase inhibitor SKF86002 lacks intrinsic fluorescence but becomes fluorescent upon binding to the ATP-binding sites of p38 mitogen-activated protein kinase (p38α). It was found that co-crystals of this compound with various kinases were distinguishable by their strong fluorescence. The co-crystals of SKF86002 with p38α, Pim1, ASK1, HCK and AMPK(More)
