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 Lethal Congenital Contracture Syndrome 7 and Autism Susceptibility 15. Among its related pathways are L1CAM interactions and Cell adhesion molecules (CAMs). GO annotations related to this gene include receptor activity and SH3/SH2 adaptor activity. An important paralog of this gene is CNTNAP2.
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.
