Question

Roderick MacKinnon crystallized one of these proteins from S. lividans that (15[1])contains a highly conserved TVGYG sequence. Tetraethylammonium is used (15[1])to experimentally inhibit these proteins. One of these proteins in humans is mutated in the most common form of Romano–Ward syndrome. That (15[1])one of these proteins is named for its homology to the Drosophila ether-a-go-go gene and is inhibited in most forms of drug-induced (*) long QT syndrome. The sulfonylurea receptor is found on an ATP-responsive one of these proteins in the islets of Langerhans (10[1])that deactivates to trigger insulin exocytosis. A mutation in another of these (10[1])proteins causes Drosophila to twitch under anesthesia and is called shaker. Inward-rectifying types of these proteins (-5[1])maintain the resting potential of neurons. (-5[2])For 10 points, name these proteins that conduct an ion that is exchanged (10[1])for sodium across (-5[1])the (10[1])membrane. (10[1])■END■ (10[2]0[2])

ANSWER: potassium channels [or K-channels; accept inward-rectifiers or IRK until “inward-rectifying” is read; prompt on membrane proteins until “membrane” is read; prompt on voltage-gated ion channels by asking “what species is being moved?”]
