Predicted to enable excitatory extracellular ligand-gated monoatomic ion channel activity; serotonin-gated monoatomic cation channel activity; and transmitter-gated monoatomic ion channel activity involved in regulation of postsynaptic membrane potential. Acts upstream of or within positive regulation of cytosolic calcium ion concentration. Predicted to be located in membrane. Predicted to be part of transmembrane transporter complex. Predicted to be active in cholinergic synapse; neuron projection; and postsynaptic specialization membrane. [provided by Alliance of Genome Resources, Apr 2025]
