Problem Set 1 Congratulations! You have just been promoted to chief scientist (and bottle-washer) for Pungent Biotech, Inc. (PBI). PBI has recently completed the cloning of all odorant GPCR cDNAs from an olfactory neuron library, a total of >300 receptors. PBI has been approached by Nintendo to help in the development of their new virtual reality gaming system which includes their proprietary STINK™ technology. STINK™ is a system that allows for the controlled release of a “puff”...

NR 565 MIDTERM FINALS 2023-204 G-Protien coupled receptors and how they interact with drugs - CORRECT ANSWERG-protein coupled receptors (GPCR) interact with drugs through 7 regions of proteins that span and innervate the cell membrane and trap the molecule into the receptor site like an interwoven basket (Insel & Sriram, 2018). Drugs can then enter this space and interact with the GRCP. A specific interaction and binding with a site on one or more of the regions of proteins within the ...
