This gene encodes a member of the neurexin gene family. The products of these genes function as cell adhesion molecules and receptors in the vertebrate nervous system. These genes utilize two promoters. The majority of transcripts are produced from the upstream promoter and encode alpha-neurexin isoforms while a smaller number of transcripts are produced from the downstream promoter and encode beta-neuresin isoforms. The alpha-neurexins contain epidermal growth factor-like (EGF-like) sequences and laminin G domains, and have been shown to interact with neurexophilins. The beta-neurexins lack EGF-like sequences and contain fewer laminin G domains than alpha-neurexins. Alternative splicing and the use of alternative promoters may generate thousands of transcript variants (PMID: 12036300, PMID: 11944992).[provided by RefSeq, Jun 2010]

功能
Neurexin 2 alpha belongs to the Neurexin family, a group of neuronal proteins that function as cell adhesion molecules during synaptogenesis and intracellular signaling. Mammalian genomes contain just three neurexin genes. However, many neurexin isoforms may be expressed through the use of two alternative promoters and alternative splicing at up to five different positions.
