of on-off switches, while others were more like dimmer switches, responding in proportion to the amount of LG335 bound to them. Doyle's team also studied their re-engineered receptors in mammalian cells and found they behaved much the same as in yea...
Amgen investigational therapy, AMG 162, increased bone mineral density with twice yearly injection

in similar ways, by interacting with G proteins to transmit signals to the cell's interior. Since many receptors of this type share certain DNA sequences, Buck designed probes that would recognize these sequences in a pool of rat DNA. Next, she assum...
