ID:CNTN1_HUMAN DESCRIPTION: RecName: Full=Contactin-1; AltName: Full=Glycoprotein gp135; AltName: Full=Neural cell surface protein F3; Flags: Precursor; 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 (By similarity). SUBUNIT: Monomer. Interacts with CNTNAP1 in cis form. Binds to the carbonic-anhydrase like domain of protein-tyrosine phosphatase zeta. Interacts with NOTCH1 and TNR (By similarity). SUBCELLULAR LOCATION: Isoform 1: Cell membrane; Lipid-anchor, GPI- anchor; Extracellular side. SUBCELLULAR LOCATION: Isoform 2: Cell membrane; Lipid-anchor, GPI- anchor; Extracellular side. TISSUE SPECIFICITY: Strongly expressed in brain and in neuroblastoma and retinoblastoma cell lines. Lower levels of expression in lung, pancreas, kidney and skeletal muscle. DISEASE: Defects in CNTN1 are the cause of Compton-North congenital myopathy (CNCM) [MIM:612540]. CNCM is a familial lethal form of congenital onset muscle weakness, inherited in an autosomal-recessive fashion and characterized by a secondary loss of beta2-syntrophin and alpha-dystrobrevin from the muscle sarcolemma, central nervous system involvement, and fetal akinesia. SIMILARITY: Belongs to the immunoglobulin superfamily. Contactin family. SIMILARITY: Contains 4 fibronectin type-III domains. SIMILARITY: Contains 6 Ig-like C2-type (immunoglobulin-like) domains.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
