glr-3 encodes a protein that contains a ligand-gated ion channel domain and a receptor family ligand binding domain with similarity to kainate-selective ionotropic glutamate receptor 2 (human GRIK2); expressed in the RIA neuron.
Predicted to enable glutamate receptor activity and transmitter-gated monoatomic ion channel activity involved in regulation of postsynaptic membrane potential. Involved in detection of cold stimulus involved in thermoception and detection of temperature stimulus involved in sensory perception of pain. Predicted to be located in postsynaptic density membrane. Human ortholog(s) of this gene implicated in temporal lobe epilepsy. Is an ortholog of human GRIK3 (glutamate ionotropic receptor kainate type subunit 3) and GRIK4 (glutamate ionotropic receptor kainate type subunit 4).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
