General annotation (Comments)
| Function | Neuronal cell surface protein thought to be involved in cell-cell-interactions by forming intercellular junctions through binding to beta-neurexins. May play a role in formation or maintenance of synaptic junctions. May also play a role in glia-glia or glia-neuron interactions in the developing peripheral nervous system. |
| Subunit structure | Interacts with neurexin 1-beta, neurexin 2-beta and neurexin 3-beta By similarity. Probably interacts through its C-terminus with DLG4/PSD-95 third PDZ domain. |
| Subcellular location | Membrane; Single-pass type I membrane proteinPotential. |
| Involvement in disease | Defects in NLGN3 may be the cause of susceptibility to X-linked autism 1 (AUTSX1) [MIM:300425]. AUTSX1 is a pervasive developmental disorder (PDD), prototypically characterized by impairments in reciprocal social interaction and communication, restricted and stereotyped patterns of interests and activities, and the presence of developmental abnormalities by 3 years of age. Defects in NLGN3 may be the cause of susceptibility to X-linked Asperger syndrome 1 (ASPGX1) [MIM:300494]. ASPGX1 is considered to be a form of childhood autism. |
| Sequence similarities | Belongs to the type-B carboxylesterase/lipase family. |
| Sequence caution | The sequence AAF71231.1 differs from that shown. Reason: Miscellaneous discrepancy. Contaminating sequence. Potential poly-A sequence. |
