(24:14) Guests: Rebecca Plimpton, PhD. Candidate in Biochemistry at BYU  Barry Willardson, Faculty Advisor in the Biochemistry Department at BYU  Your ability to react fast – and without having to think “Okay, I need adrenaline” – is a result of a special class of protein that has long mystified scientists. So-called “G” Proteins are like the switchboard operators in your cells, telling various processes when to turn on and off.  “We were actually looking for something that happens with G proteins before its attached to the cell membrane. All proteins when they are made start out as a long string of atoms all connected together and in order for the G protein to perform its function that string has to fold into a 3-dimensional, precise shape. Our research looks at how the proteins fold into this shape,” says Plimpton.
