Neuroligins (Nlgns) are a family of postsynaptic transmembrane cell adhesion proteins that play a crucial role in excitation and inhibition balance through their regulation of GABAergic and glutamatergic signaling. 5 Neuroligin family members have been identified in humans: NL1, NL2, NL3, NL4X, and NL4Y. NL 1-3 have close homologs in mice. Neurogilins have been identified in rodents, chicken, Drosophila, and C. elegans.
Neuroligin structure contains extracellular acetylcholinesterase like domain that lacks esterase activity, a single transmembrane domain, and a short cytoplasmic tail containing a type I PDZ-domain-binding motif that functions in intracellular protein-protein interactions and signaling processes. Neuroligins and neurexins are known to interact with each other1,2.
Neuroligin 3 is encoded by the Nlgn3 gene and seems to be ubiquitously expressed in the brain. Despite this fact, Neuroligin 3 functions in synaptic transmission appears to be region specific, affecting the somatosensory cortex and the hippocampus differently2.
In humans, a missense mutation in Nlgn3 (Nlgn3R451C) causing reduced synaptic expression of the protein is associated with non-syndromic autism spectrum disorders. In addition, Nlgn3 deletion shows impaired social interaction and vocal communication in rodent models.
Species reactivity key:
Anti-Neuroligin 3 (extracellular) Antibody (#ANR-037) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, analysis. The antibody recognizes an extracellular epitope, and could potentially be used for detecting the protein in living cells. It has been designed to recognize NLGN3 from rat, mouse, and human samples.
