Summaries for CNTNAP1 Gene

Entrez Gene Summary for CNTNAP1 Gene

  • The gene product was initially identified as a 190-kD protein associated with the contactin-PTPRZ1 complex. The 1,384-amino acid protein, also designated p190 or CASPR for 'contactin-associated protein,' includes an extracellular domain with several putative protein-protein interaction domains, a putative transmembrane domain, and a 74-amino acid cytoplasmic domain. Northern blot analysis showed that the gene is transcribed predominantly in brain as a transcript of 6.2 kb, with weak expression in several other tissues tested. The architecture of its extracellular domain is similar to that of neurexins, and this protein may be the signaling subunit of contactin, enabling recruitment and activation of intracellular signaling pathways in neurons.

GeneCards Summary for CNTNAP1 Gene

CNTNAP1 (Contactin Associated Protein 1) is a Protein Coding gene. Diseases associated with CNTNAP1 include hypomyelination neuropathy - arthrogryposis and lethal congenital contracture syndrome 7. Among its related pathways are Developmental Biology and L1CAM interactions. GO annotations related to this gene include receptor activity and SH3/SH2 adaptor activity. An important paralog of this gene is CNTNAP3.

UniProtKB/Swiss-Prot for CNTNAP1 Gene

  • Seems to play a role in the formation of functional distinct domains critical for saltatory conduction of nerve impulses in myelinated nerve fibers. Seems to demarcate the paranodal region of the axo-glial junction. In association with contactin may have a role in the signaling between axons and myelinating glial cells

  • Lethal congenital contracture syndrome 7 (LCCS7) [MIM:616286]: A form of lethal congenital contracture syndrome, an autosomal recessive disorder characterized by degeneration of anterior horn neurons, extreme skeletal muscle atrophy and congenital non-progressive joint contractures. The contractures can involve the upper or lower limbs and/or the vertebral column, leading to various degrees of flexion or extension limitations evident at birth. LCCS7 is a severe axoglial disease characterized by congenital distal joint contractures, polyhydramnios, reduced fetal movements, and motor paralysis leading to death early in the neonatal period. {ECO:0000269 PubMed:24319099}. Note=The disease is caused by mutations affecting the gene represented in this entry.
