Summary: The protein encoded by this gene is a critical subunit of N-methyl-D-aspartate receptors, members of the glutamate receptor channel superfamily which are heteromeric protein complexes with multiple subunits arranged to form a ligand-gated ion channel. These subunits play a key role in the plasticity of synapses, which is believed to underlie memory and learning. Cell-specific factors are thought to control expression of different isoforms, possibly contributing to the functional diversity of the subunits. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2008]

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

See identical proteins and their annotated locations for NP_000823.4

Status: REVIEWED

Description

Transcript Variant: This variant (GluN1-4a, also known as NR1-1) lacks an alternate in-frame exon and uses an alternate splice site in the 3' coding region, compared to variant GluN1-1a. The resulting protein (isoform GluN1-4a, also known as isoform NR1-1) is shorter and has a different C-terminus, compared to isoform GluN1-1a.
