LITERATURE
ENZYME 3D STRUCTURE
inhibits the reduction of 20alpha-hydroxy-pregn-4-en-3-one to progesterone competitively
-
inhibits IKK
-
dose-dependent inhibition with maximal effect at 1 nM. The addition of 0.001 mM prostaglandin E2 decreases Na+-ATPase activity by 41%. The inhibitory effect of prostaglandin E2 on proximal tubule Na+-ATPase activity involves G protein and the activation of protein kinase A. The protein A-mediated inhibitory effect of prostaglandin E2 on Na+-ATPase activity requires previous activation of protein kinase C
