Comments
  • FUNCTION: Putative neuronal cell surface protein involved in cell-cell-interactions.
  • SUBUNIT: Interacts through its C-terminus with DLG4/PSD-95 third PDZ domain.
  • SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein (Potential).
  • ALTERNATIVE PRODUCTS: 2 named isoforms [FASTA] produced by alternative splicing.
    Name1
    Isoform IDQ8N0W4-1
    This is the isoform sequence displayed in this entry.
    Name2
    Isoform IDQ8N0W4-2
    Note: No experimental confirmation available.
    Features which should be applied to build the isoform sequence: VSP_013270.
  • TISSUE SPECIFICITY: Expressed at highest levels in heart. Expressed at lower levels in liver, skeletal muscle and pancreas and at very low levels in brain.
  • DISEASE: Defects in NLGN4X may be the cause of susceptibility to X-linked autism 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.
  • DISEASE: 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.
  • SIMILARITY: Belongs to the type-B carboxylesterase/lipase family.
  • WEB RESOURCE: Name=GeneReviews; URL="http://www.genetests.org/query?gene=NLGN4X";.
