  • Immunofluorescence staining of A549 cells with CSB-PA623657LA01HU at 1:66, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

Target Background

Function
Contactins mediate cell surface interactions during nervous system development. Involved in the formation of paranodal axo-glial junctions in myelinated peripheral nerves and in the signaling between axons and myelinating glial cells via its association with CNTNAP1. Participates in oligodendrocytes generation by acting as a ligand of NOTCH1. Its association with NOTCH1 promotes NOTCH1 activation through the released notch intracellular domain (NICD) and subsequent translocation to the nucleus. Interaction with TNR induces a repulsion of neurons and an inhibition of neurite outgrowth.

  2. Proteolipid protein 1 and contactin 1 gene variation modulates interhemispheric integration PMID: 27864734
  3. CNTN-1 promotes cisplatin resistance in human cisplatin-resistant lung adenocarcinoma through inducing the Epithelial-Mesenchymal Transition process by activating the PI3K/Akt signaling pathway. PMID: 28934754
  4. CNTN1 is a new gene which can be regulated by RET/PTC3 (Ret proto-oncogene and Ret-activating protein ELE1) rearrangement gene and the protein level of CNTN1 is increasing in thyroid cancer. PMID: 26722434
  5. Structurally, CASPR2 is highly glycosylated and has an overall compact architecture. CASPR2 associates with micromolar affinity with CNTN1 but, under the same conditions, it does not interact with any of the other members of the contactin family. PMID: 26721881

  12. A high expression of CNTN1 was markedly associated with the regional lymph node metastasis of patients with oral squamous cell carcinoma. PMID: 22580838
  13. The expression of CNTN-1 is upregulated in esophageal squamous cell carcinoma tissue and is related to stage and lymphatic invasion. Thus, it may be involved in the pathogenesis & progression of esophageal squamous cell carcinoma. PMID: 22581910
  14. Data revealed that knockdown of VEGFR-3 with the shRNA lentiviral vector resulted in down-regulation of the downstream neural cell adhesion molecule contactin-1 (CNTN-1). PMID: 21805024
  15. report the cocrystal structure of the carbonic anhydrase-like domain of PTPRZ bound to tandem Ig repeats of CNTN1 and binding assays to show that PTPRZ binds specifically to CNTN1 expressed at the surface of oligodendrocyte precursor cells PMID: 21969550
  16. VEGF-C mediated biological function through transcription of CNTN-1, which is implicated in tumor invasion and metastasis. PMID: 21482472
  17. F3 acts as a functional ligand for Notch during oligodendrocyte maturation. PMID: 14567914
  18. The repulsive properties of contactin may be a key factor in glioma disaggregation, and may contribute to the diffuse infiltration pattern characteristic of glioma cells in human brain. PMID: 16078236
  19. Contactin-1 is proposed to function importantly in the invasion and metastasis of lung adenocarcinoma cells via RhoA-mediated mechanisms. PMID: 16510572
