Summary: Predicted to enable glutamate receptor activity and transmitter-gated monoatomic ion channel activity involved in regulation of postsynaptic membrane potential. Predicted to be involved in glutamatergic synaptic transmission and modulation of chemical synaptic transmission. Predicted to be located in postsynaptic membrane. Predicted to be active in postsynaptic density membrane. Is expressed in several structures, including M1 neuron; RMD; interneuron; linker cell; and nerve ring. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder; autosomal recessive intellectual developmental disorder 76; epilepsy; schizophrenia; and syndromic X-linked intellectual disability 94. Orthologous to several human genes including GRIA1 (glutamate ionotropic receptor AMPA type subunit 1); GRIA2 (glutamate ionotropic receptor AMPA type subunit 2); and GRIA3 (glutamate ionotropic receptor AMPA type subunit 3).

What's a GeneRIF?

previously-stimulated animals later habituate to subsequent mechanostimulation more rapidly compared to animals initially reared without mechanical stimulation; MAGI-1L, GLR-1, and GLR-2 are required for this change in habituation kinetics.
Title: MAGI-1 modulates AMPA receptor synaptic localization and behavioral plasticity in response to prior experience.
unfolded protein response signaling is a critical step in neural function that is needed for GLR-1, GLR-2, and GLR-5 assembly and secretion
Title: The unfolded protein response regulates glutamate receptor export from the endoplasmic reticulum.
An arginine residue was introduced into the pore loop of glutamate receptor subunit, GLR-2. Synaptically activated GLR-2R-containing iGluR channels appear to trigger inappropriate, neurotoxic Ca2+ release from intracellular stores.
Title: Neuronal toxicity in Caenorhabditis elegans from an editing site mutant in glutamate receptor channels.
results show that while the osmotic avoidance response requires both NMDA and non-NMDA receptors, the response to mechanical stimuli only requires non-NMDA receptors
Title: Decoding of polymodal sensory stimuli by postsynaptic glutamate receptors in C. elegans.
Cytosolic tail sequences and subunit interactions of GLR-1 and GLR-2 are critical for synaptic localization of glutamate receptors
