Signal transduction is the fundamental process by which cells convert external cues into tailored intracellular responses. Through a cascade of molecular events—beginning at the cell membrane with the ...

The most diverse functions of a cell in the human body – from cell division and differentiation to motility and programmed cell death – are controlled by signaling proteins within the cell. This ...

This paper describes the isolation, cloning, and molecular characterization of a receptor molecule for calcium ions located on the outer surface of certain types of cells. The reason it has received ...

cases an external molecule dramatically affects cellular function. Our goal in studying any of these processes is the same: a molecule-by-molecule accounting of information transfer in biological ...
