MGI Phenotype FUNCTION: This gene encodes a single-pass type I membrane protein that belongs to the neurexin family. Neurexins are synaptic transmembrane receptors that bind endogenous ligands that include neuroligins, dystroglycan, and neurexophilins. Neurexin complexes are required for efficient neurotransmission and are involved in synaptogenesis. In vertebrates, alternate promoter usage results in multiple isoform classes, of which the alpha and beta classes are the best characterized. In humans, allelic variants in this gene are associated with Pitt-Hopkins-like syndrome-2, while deletions have been associated with autism and schizophrenia. Mouse knockouts display decreased spontaneous and evoked vesicle release resulting in impaired synaptic transmission. In addition, knockout mice show altered social approach, reduced social investigation, reduced locomotor activity, and in males, increased aggression. Alternative splicing and promoter usage result in multiple transcript variants. [provided by RefSeq, Nov 2016]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit reduced Ca(2+)-dependent binding of alpha-latrotoxin to brain membranes. Isolated synaptosomes display only a small reduction in alpha-latrotoxin -triggered glutamate release in the absence of Ca(2+) but show a major decrease in the presence of Ca(2+).
