Summaries for GRIN3B Gene

Entrez Gene Summary for GRIN3B Gene

  • The protein encoded by this gene is a subunit of an N-methyl-D-aspartate (NMDA) receptor. The encoded protein is found primarily in motor neurons, where it forms a heterotetramer with GRIN1 to create an excitatory glycine receptor. Variations in this gene have been proposed to be linked to schizophrenia. [provided by RefSeq, Nov 2015]

GeneCards Summary for GRIN3B Gene

GRIN3B (Glutamate Receptor, Ionotropic, N-Methyl-D-Aspartate 3B) is a Protein Coding gene. Diseases associated with GRIN3B include lingual-facial-buccal dyskinesia and opioid abuse. Among its related pathways are Amphetamine addiction and RNA Polymerase I Promoter Opening. GO annotations related to this gene include calcium channel activity and ionotropic glutamate receptor activity. An important paralog of this gene is GRIN2A.

UniProtKB/Swiss-Prot for GRIN3B Gene

  • NMDA receptor subtype of glutamate-gated ion channels with reduced single-channel conductance, low calcium permeability and low voltage-dependent sensitivity to magnesium. Mediated by glycine

Tocris Summary for GRIN3B Gene

  • NMDA receptors are members of the ionotropic class of glutamate receptors, which also includes Kainate and AMPA receptors. NMDA receptors consist of NR1 subunits combined with NR2 (A-D) or NR3 (A-B) subunits. The ligand-gated channel is permeable to cations.
