Eva Julia Neer (1937–2000) was an American physician (Columbia University P&S), biochemist, and cell-biology scientist who gained U.S. national research awards (FASEB 1987 & American Heart Association 1996) for her discoveries on G-protein subunit structure and function. She described the physiological roles of these subunits as an integrated and versatile molecular system of signal transduction for membrane-receptor regulation of cell function. Her research concepts turned her into a world leader in G-protein studies and impinged widely on the general understanding of cell behavior.[1][2][3]
