REVISITED CRYSTAL STRUCTURE OF NEUREXIN1BETA-NEUROLIGIN4 COMPLEX

Template:ABSTRACT PUBMED 20543817

Disease

[NLGNX_HUMAN] Defects in NLGN4X may be the cause of susceptibility to autism X-linked type 2 (AUTSX2) [MIM:300495]. AUTSX2 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.[1] Defects in NLGN4X may be the cause of susceptibility to X-linked Asperger syndrome 2 (ASPGX2) [MIM:300497]. ASPGX2 is considered to be a form of childhood autism.

Function

[NLGNX_HUMAN] Putative neuronal cell surface protein involved in cell-cell-interactions. [NRX1B_RAT] Neuronal cell surface protein that may be involved in cell recognition and cell adhesion by forming intracellular junctions through binding to neuroligins. May play a role in formation or maintenance of synaptic junctions. May mediate intracellular signaling. May play a role in angiogenesis (By similarity).[2]

About this Structure
