At least 16 distinct subunits of GABA receptors have been identified.

The encoded protein is one of at least 13 distinct subunits of a multisubunit chloride channel that serves as the receptor for gamma-aminobutyric acid, the major inhibitory transmitter of the nervous system.

Each toxin consists of three distinct subunits named alphabetically in the order that their coding genes appear in the cdt operon.

The active, assembled toxin is a tripartite structure with three distinct subunits- CdtA, CdtB, and CdtC.

ATP citrate synthase is composed of two distinct subunits.

A member is a minor unit in a formation and a bed is a distinct subunit of a member.

There are now at least 13 genetically distinct small subunit ribosomal RNA lineages.

G-proteins exist as a heterotrimer; they are composed of three distinct subunits.

MaxiK channels can contain two distinct subunits: a pore-forming alpha subunit and a modulatory beta subunit.

The family of enzymes to which ASL belongs and that catalyze β-eliminations in which fumarate is one of the products are homotetramers with four active sites composed of amino acid residues from three distinct subunits.
