Mapping the key signaling molecules in biochemical pathways will be central to future drug discovery efforts. Signal transduction describes the process of conversion of external signals ...

Davis, University of Massachusetts Medical School, Howard Hughes Medical Institute. The signal transduction pathways of mitogen-activated protein (MAP) kinases have been actively studied for some time ...

One example is follicle-stimulating hormone ... cell and subsequently transmit the signal through a sequence of molecular switches to internal signaling pathways. Membrane receptors fall into ...

Saltiel, department of signal transduction, Parke-Davis, Ann Arbor, Mich. The chemical signals triggering cellular growth resemble multiple pathways more closely than a single trail. Consequently, ...
