3D protein structure reveals new drug targets for cancer.

In collaboration with the study group of Susan Taylor, PhD, professor of pharmacology at UC San Diego School of Medicine, Newton and experts took another appearance at how exactly to connect the right parts, or domains, of the enzyme. They came up with a different framework and tested it utilizing a sophisticated cellular imaging strategy to visualize whether PKC was correctly loaded together or not. The researchers discovered that PKC's calcium-sensing domain interacts using its own tail and enzymatic domain , locking the enzyme in an inactive pose. PKC starts to activate when calcium triggers the bridging of the C2 domain to the cell membrane, starting the enzyme for activity thus.Holme, Ph.D., David Kallend, M.B., B.S., Lawrence A.
