WebbReceptors, located on both the cell surface and within the cell, are the molecular targets through which drugs produce their beneficial effects in various disease states. Receptors were initially conceptualized at the beginning of the 20th century by the parallel efforts of Ehrlich and Langley. WebbProtein kinase C does not have any known nuclear localization signal but, nevertheless, is redistributed from the cytoplasm to the nucleus upon various stimuli. In NIH 3T3 fibroblasts stimulation with phorbol ester leads to a translocation of protein kinase C alpha to the plasma membrane and into the cell nucleus. We compared the mechanism of …
