Gene ID: 9378 | Gene type: protein coding

About NRXN1

Cytogenetic location: 2p16.3 Genomic coordinates (GRCh38): 2:49,918,503-51,032,132 (from NCBI)

This gene has 65 transcripts (splice variants), 238 orthologues, 35 paralogues and is associated with 6 phenotypes. Biased expression in brain (RPKM 12.7) and testis (RPKM 0.6).

Summary

This gene encodes a single-pass type I membrane protein that belongs to the neurexin family. Neurexins are cell-surface receptors that bind neuroligins to form Ca(2+)-dependent neurexin/neuroligin complexes at synapses in the central nervous system. This complex is required for efficient neurotransmission and is involved in the formation of synaptic contacts. Three members of this gene family have been studied in detail and are estimated to generate over 3,000 variants through the use of two alternative promoters (alpha and beta) and extensive alternative splicing in each family member. Recently, a third promoter (gamma) was identified for this gene in the 3' region. Mutations in this gene are associated with Pitt-Hopkins-like syndrome-2 and may contribute to susceptibility to schizophrenia. [provided by RefSeq, Aug 2016]
