kainatereseptorit
Kainatereseptorit, known in English as kainate receptors, are a subfamily of ionotropic glutamate receptors (iGluRs) that mediate excitatory neurotransmission in the central nervous system. They form tetrameric ligand-gated ion channels composed of subunits GluK1–GluK5, encoded by the GRIK1–GRIK5 genes. Subunits can assemble as homo- or heteromeric complexes, yielding receptors with distinct biophysical and pharmacological properties.
Kainate receptors are located at both postsynaptic and presynaptic sites throughout the brain, notably in the
Activation by glutamate or kainic acid elicits excitatory currents; researchers employ selective agonists and antagonists to
In Finnish sources, these receptors are referred to as kainatereseptorit, paralleling the English term. They are
