Contactin-2 (CNTN2)

Target (abbrv.) CNTN2
Target (full name) Contactin-2
Somalogic ID (Sequence ID) SL008623 (3296-92_2)
Entrez Gene Symbol CNTN2
UniProt ID Q02246
UniProt Comment
  • In conjunction with another transmembrane protein, CNTNAP2, contributes to the organization of axonal domains at nodes of Ranvier by maintaining voltage-gated potassium channels at the juxtaparanodal region. May be involved in cell adhesion.
  • L1CAM interactions
  • NCAM1 interactions
  • NrCAM interactions

All locus annotations are based on the sentinel SNP (rs2246662) and 1 proxy variant(s) that is/are in linkage disequilibrium r2 ≥ 0.8. Linkage disequilibrium is based on data from the 1000 Genomes Project, phase 3 version 5, European population and was retrieved using SNiPA's Block Annotation feature.
