Function
Member of the ionotropic glutamate receptor family, which plays a crucial role in synaptic organization and signal transduction in the central nervous system. Although it shares structural features with ionotropic glutamate receptors, does not bind glutamate as a primary ligand (PubMed:34936451). Promotes synaptogenesis and mediates the D-Serine-dependent long term depression signals and AMPA receptor endocytosis of cerebellar parallel fiber-Purkinje cell (PF-PC) synapses through the NRX1B-CBLN1-GRID2 triad complex (PubMed:27418511). In the presence of neurexins and cerebellins, forms cation-selective channels that are proposed to be gated by glycine and D-serine (PubMed:34936451). However, recent research disputes this ligand-gated cation channel activity (PubMed:39052831). Cation-selective ion channel activity can be triggered by GRM1 in Purkinje cells (PubMed:24357660, PubMed:27276689).

- Activity summary
The gene symbol 'GRID2' encodes the protein Glutamate Receptor Ionotropic Delta-2 commonly called GRID2. It is part of the ionotropic glutamate receptor family and functions as ion channels in the central nervous system. GRID2 has an approximate mass of 110 kDa and is principally expressed in the cerebellum. This protein receptor plays a role in excitatory synaptic transmission by binding glutamate an essential neurotransmitter. It is not widespread in the body but has critical functions where it is present.
- Biological function summary
The GRID2 protein is significant in synaptic plasticity and cerebellar functions by contributing to synapse formation and stability. It is part of the postsynaptic density (PSD) complex in neurons mainly affecting the communication between neuron cells. This protein helps in maintaining proper synaptic connections necessary for motor coordination and learning. The deficit of GRID2 can disrupt these functions affecting synaptic efficacy and neurological behavior.
- Pathways
Grid ionotropic receptors like GRID2 play a pivotal role in the glutamatergic pathway and the synaptic signaling pathway. These pathways have strong associations with synaptic transmission and plasticity influencing learning and memory. The relationship of GRID2 with other proteins such as GRIA1 another glutamate receptor highlights its involvement in regulating synaptic strength and communication between neurons.
- Associated diseases and disorders
GRID2 mutations or dysfunctions link to neurological conditions such as spinocerebellar ataxia and autism spectrum disorders. Spinocerebellar ataxia patients show mutations that alter GRID2 function impacting motor coordination. In some autism spectrum disorder cases alterations in GRID2-supported pathways can influence synaptic connectivity which affects cognitive and social functioning. Connections with other proteins like GRIK2 suggest a network where GRID2 dysfunction contributes to these disease symptoms.
