HTR3A, are large biomolecules, or macromolecules, causes fast, depolarizing responses in neurons after activation and the A subunit forms homomers with a very low single channel conductance of 0.6pS.
5-hydroxytryptamine receptor 3A is a protein that in humans is encoded by the HTR3A gene. Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. This receptor causes fast, depolarizing responses in neurons after activation. The A subunit is the only one that can be expressed alone and forms homomers with a very low single channel conductance of 0.6pS.
