Protein

Glutamate [NMDA] receptor subunit 1

Gene

Nmdar1

Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

NMDA receptor subtype of glutamate-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium. Mediated by glycine. This protein plays a key role in synaptic plasticity, synaptogenesis, excitotoxicity, memory acquisition and learning. It mediates neuronal functions in glutamate neurotransmission. Is involved in the cell surface targeting of NMDA receptors. Plays a role in associative learning and in long-term memory consolidation.By similarity1 Publication

Expressioni

Tissue specificityi

Highly expressed in adult heads: in the brain and ring gland. Low expression throughout the entire brain is also seen. Higher expression levels were observed in some scattered cell bodies and part of their fibers, including those from several pairs of DPM (dorsal-posterior-medial) neurons surrounding the calyx, DAL (dorsal-anterior-lateral) and DPL (dorsal-posterior-lateral) neurons in the lateral protocerebrum (LP), VAL (ventral-anterior-lateral) neurons in the anterior protocerebrum, and two pairs of VP (ventral-posterior) neurons in the posterior protocerebrum. Many cell bodies in the optic lobes show preferential expression. Punctuate expression is notably detected in many brain regions including the superior medial protocerebrum. Weakly expressed in the antennal lobes and central complex.3 Publications

Developmental stagei

Expression first seen in late embryos. Levels are low during larval development and increase in late pupae to persist through to adulthood.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
