Interacting selectively and non-covalently with choline, the amine 2-hydroxy-N,N,N-trimethylethanaminium. Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. Interacting selectively and non-covalently with a quaternary ammonium group, including glycine betaine, choline, carnitine and proline. A quaternary ammonium group is any compound that can be regarded as derived from ammonium hydroxide or an ammonium salt by replacement of all four hydrogen atoms of the NH4+ ion by organic groups. The selective, non-covalent, often stoichiometric, interaction of a molecule with one or more specific sites on another molecule. Interacting selectively and non-covalently with phosphatidylcholine, a class of glycophospholipids in which a phosphatidyl group is esterified to the hydroxyl group of choline.
