Automated description from the Alliance of Genome Resources (Release 3.0)
Exhibits ligand-gated ion channel activity involved in regulation of presynaptic membrane potential. Predicted to be involved in several processes, including G protein-coupled glutamate receptor signaling pathway; glutamatergic synaptic transmission; and negative regulation of glutamatergic synaptic transmission. Localizes to glutamatergic synapse and plasma membrane. Is expressed in several structures, including brain; chordamesoderm; embryo endoderm; future brain; and hindgut diverticulum. Orthologous to human GRIK3 (glutamate ionotropic receptor kainate type subunit 3).
