dopamine binding

Interacting selectively and non-covalently with dopamine, a catecholamine neurotransmitter formed by aromatic-L-amino-acid decarboxylase from 3,4-dihydroxy-L-phenylalanine.

cocaine binding

Interacting selectively and non-covalently with cocaine (2-beta-carbomethoxy-3-beta-benzoxytropane), an alkaloid obtained from dried leaves of the South American shrub Erythroxylon coca or by chemical synthesis.

G protein-coupled amine receptor activity

Combining with an extracellular amine and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex.

amorpha-4,11-diene 12-monooxygenase activity

Catalysis of the reaction:(+)-amorpha-4,11-diene + 3 O2 + 3 reduced [NADPH--hemoprotein reductase] = (+)-artemisinate + 4 H(+) + 4 H2O + 3 oxidized [NADPH--hemoprotein reductase]

voltage-gated potassium channel activity

Enables the transmembrane transfer of a potassium ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.

voltage-gated cation channel activity

Enables the transmembrane transfer of a cation by a voltage-gated channel. A cation is a positively charged ion. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.

potassium channel activity

Enables the facilitated diffusion of a potassium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.

voltage-gated chloride channel activity

Enables the transmembrane transfer of a chloride ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.

voltage-gated anion channel activity

Enables the transmembrane transfer of an anion by a voltage-gated channel. An anion is a negatively charged ion. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.

chloride channel activity

Enables the facilitated diffusion of a chloride (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.

antioxidant activity

Inhibition of the reactions brought about by dioxygen (O2) or peroxides. Usually the antioxidant is effective because it can itself be more easily oxidized than the substance protected. The term is often applied to components that can trap free radic

selective, non-covalent, often stoichiometric, interaction of a molecule with one or more specific sites on another molecule
