  ID: CNTP2_HUMAN
DESCRIPTION: RecName: Full=Contactin-associated protein-like 2; AltName: Full=Cell recognition molecule Caspr2; Flags: Precursor;
FUNCTION: May 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 juxtaparanodal region of the axo-glial junction.
SUBUNIT: Associates with KCNA2 (By similarity).
SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein (Potential).
TISSUE SPECIFICITY: Predominantly expressed in nervous system.
DISEASE: Defects in CNTNAP2 are the cause of cortical dysplasia- focal epilepsy syndrome (CDFES) [MIM:610042]. Affected individuals manifest cortical dysplasia, focal epilepsy, relative macrocephaly, and diminished deep-tendon reflexes. Intractable focal seizures begin in early childhood, after which language regression, hyperactivity, impulsive and aggressive behavior, and mental retardation develop.
DISEASE: Genetic variations in CNTNAP2 influences susceptibility to autism type 15 (AUTS15) [MIM:612100]. Autism is a neurodevelopmental disorder characterized by disturbance in language, perception and socialization. The disorder is classically defined by a triad of limited or absent verbal communication, a lack of reciprocal social interaction or responsiveness, and restricted, stereotypical, and ritualized patterns of interests and behavior.
DISEASE: Note=A chromosomal aberration involving CNTNAP2 is found in a patient with autism spectrum disorder. Paracentric inversion 46,XY,inv(7)(q11.22;q35). The inversion breakpoints disrupt the genes AUTS2 and CNTNAP2.
SIMILARITY: Belongs to the neurexin family.
SIMILARITY: Contains 2 EGF-like domains.
SIMILARITY: Contains 1 F5/8 type C domain.
SIMILARITY: Contains 1 fibrinogen C-terminal domain.
SIMILARITY: Contains 4 laminin G-like domains.
SEQUENCE CAUTION: Sequence=BAA74891.1; Type=Erroneous initiation;

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.
