    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]

    RefSeqs maintained independently of Annotated Genomes

    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.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (alpha2) results from the use of the 5'-most promoter, referred to as alpha. It represents the longest transcript that encodes the longest isoform (alpha2) of the representative RefSeq variants. This isoform contains EGF-like, several laminin G, and syndecan domains.

      Description
      Transcript Variant: This variant (gamma1) results from the use of an alternate promoter, referred to as gamma. It contains an alternate 5' terminal exon and lacks all the exons, except the last two 3' terminal exons, compared to variant alpha2. Hence, the encoded isoform (gamma1) is considerably shorter with a distinct N-terminus lacking the EGF-like and laminin G domains, and containing only the syndecan domain compared to isoform alpha2.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (alpha1) results from the use of the 5'-most promoter, referred to as alpha. It lacks two in-frame exons and uses an alternate in-frame donor splice site at an internal exon compared to variant alpha2. The resulting isoform (alpha1) is shorter missing a few internal protein segments compared to isoform alpha2. This isoform contains EGF-like, several laminin G, and syndecan domains.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (beta1) results from the use of an alternate promoter, referred to as beta. It contains an alternate 5' terminal exon and lacks most of the 5' exons and another exon in the 3' region compared to variant alpha2. The resulting isoform (beta1) is shorter with a distinct N-terminus lacking the EGF-like domain and containing fewer laminin G domains compared to isoform alpha2.
