Homo sapiens (Human) Neuroligin 1 KIAA1070 protein

Comment
Cell surface protein involved in cell-cell-interactions via its interactions with neurexin family members. Plays a role in synapse function and synaptic signal transmission, and probably mediates its effects by recruiting and clustering other synaptic proteins. May promote the initial formation of synapses, but is not essential for this. In vitro, triggers the de novo formation of presynaptic structures. May be involved in specification of excitatory synapses. On chromosome 3 q26.31 twice the begining (first exons AC026099.3.74552.122231 and AC069531.6.1.37580.120969) and then 630 kb further the rest of sequence in one exon?! AC008120.17.1.138779.25769. A frameshift mutation, c.875_876insTT, in the neuroligin 1 gene (NLGN1) in a patient with AD and familial history of AD. The insertion generates a premature stop codon in the extracellular domain of NL1 (p.Thr271fs). Expression of mutant NL1 shows accumulation of truncated NL1 proteins in the endoplasmic reticulum
