Staurosporine 118-131 leukotriene C4 synthase Homo sapiens 170-183 8190095-7 1994 Measurement of LTC4 synthase enzymatic activity in cells challenged with A23187 and PMA in the presence or absence of staurosporine demonstrated that the activity of the LTC4 synthase enzyme was inhibited in cells costimulated with A23187 and PMA and that inhibition could also be completely prevented by the presence of staurosporine. Staurosporine 321-334 leukotriene C4 synthase Homo sapiens 170-183 8190095-8 1994 Because PMA is known to activate PKC, and staurosporine and bisindolylmaleimide are inhibitors of PKC, these results suggest that LTC4 synthase in HL-60 cells may be phosphoregulated. Staurosporine 42-55 leukotriene C4 synthase Homo sapiens 130-143
