Round 10: Tossup 3

N-type inactivation of the slo1 (“slow-one”) type of these proteins can be described by the ball-and-chain model. One of these proteins uses the conserved (10[1])TVGYG sequence as a “selectivity filter.” The “long-lasting” type of another class of these proteins is resistant to omega-conotoxins but not to dihydropyridines (“di-hydro-pyridines”). Metabotropic glutamate receptors are contrasted with these proteins that are alternatively activated by NMDA. Two-pore-domains are found in the “leak” (10[1])type of these proteins, other types of which include inward and outward rectifying classes. Inhibitors of these proteins like tetrodotoxin are tested (10[1])using patch clamps. (10[1])Delayed voltage (-5[1])gating (10[1])of two different types of these proteins generates action potentials. (-5[1])For 10 points, name these membrane proteins (-5[1])that allow charged species to pass through. ■END■ (0[5])
