Human Contactin Associated Protein-Like 2 (CNTNAP2) interaction partners

  1. Bi-allelic aberrations (mutations and copy number variants) in CNTNAP2 in eight individuals with intellectual disability and epilepsy were reported.

  2. Older age is a strong predictor of CNS involvement in patients seropositive for CASPR2-IgG or LGI1 (show LGI1 Proteins)-IgG. Pain, peripheral manifestations, and stereotypic paroxysmal dizziness spells are common with LGI1 (show LGI1 Proteins)-IgG.

  3. Caspr2 antibodies associate with a treatable disorder that predominantly affects elderly men. The resulting syndrome may vary among patients but it usually includes a set of well-established symptoms.

  4. The molecular shape and dimensions of CNTNAP2 place constraints on how CNTNAP2 integrates in the cleft of axo (show MARCH7 Proteins)-glial and neuronal contact sites and how it functions as an organizing and adhesive molecule.

  5. A significant association was found between rs7794745 CNTNAP2 gene polymorphism and autism in an Iranian population.

  6. rs7794745 in the CNTNAP2 gene was associated with autistic spectrum disorder in Brazilian patients.

  7. we could not detect any significant association with the CNTNAP2 gene and high functioning autism

  8. CNTNAP2 is transcriptionally regulated by FOXP2 (show FOXP2 Proteins).

  9. Structurally, CASPR2 is highly glycosylated and has an overall compact architecture. CASPR2 associates with micromolar affinity with CNTN1 (show CNTN1 Proteins) but, under the same conditions, it does not interact with any of the other members of the contactin family.

  10. Results indicate that the CNTNAP2 gene may confer vulnerability to speech sound disorder

Mouse (Murine) Contactin Associated Protein-Like 2 (CNTNAP2) interaction partners

  1. After middle cerebral artery occlusion mice demonstrate profoundly impaired socially evoked USVs. In addition, there is suppression of the language-associated transcription factor,contactin-associated protein 2 (Cntnap2).

  2. Olfaction-based behavioral tests revealed that mice lacking Caspr2 exhibit abnormal response to sensory stimuli and lack preference for novel odors.

  3. Mice with the Cntnap2 genetic mutation showed a dissociation of auditory-processing abilities

  4. Study reports behavioral characterization of mouse models of autism with null mutation in Cntnap2 gene. It shows hyperactivity, mild gait phenotype and reduced vocalizations among others.

  5. new dendritic spines in mice lacking CNTNAP2 were formed at normal rates, but failed to stabilize. Notably, rates of spine elimination were unaltered, suggesting a specific role for CNTNAP2 in stabilizing new synaptic circuitry

  6. Cntnap2 deletion selectively impairs perisomatic hippocampal inhibition while sparing excitation provide additional support for synaptic dysfunction as a common mechanism underlying autism spectrum disorders

  7. The CASPR2/MUPP1 receptor complex co-localized with GPR37 (show GPR37 Proteins) in hippocampal neurons.

  8. Interaction proteomics revealed the interactors of Caspr2, including CNTN2 (show CNTN2 Proteins), KCNAs, members of the ADAM family (ADAM22 (show ADAM22 Proteins), ADAM23 (show Adam23 Proteins) and ADAM11 (show ADAM11 Proteins)), members of LGI family and MAGUKs (DLGs and MPPs (show MPHOSPH6 Proteins)).

  9. CNTNAP2 has a role in the correct trafficking of GluA1 (show GRIA1 Proteins) AMPA (show GRIA3 Proteins)-type glutamate (show GRIN1 Proteins) receptors

  10. Caspr2 is required for paranodal clustering of Kv1 (show KCNA5 Proteins) channels in the absence of Caspr (show CNTNAP1 Proteins). Absence of both Caspr (show CNTNAP1 Proteins) and Caspr2 results in the widening of the nodes of Ranvier.

CNTNAP2 Protein Profile

Protein Summary

This gene encodes a member of the neurexin family which functions in the vertebrate nervous system as cell adhesion molecules and receptors. This protein, like other neurexin proteins, contains epidermal growth factor repeats and laminin G domains. In addition, it includes an F5/8 type C domain, discoidin/neuropilin- and fibrinogen-like domains, thrombospondin N-terminal-like domains and a putative PDZ binding site. This protein is localized at the juxtaparanodes of myelinated axons, and mediates interactions between neurons and glia during nervous system development and is also involved in localization of potassium channels within differentiating axons. This gene encompasses almost 1.5% of chromosome 7 and is one of the largest genes in the human genome. It is directly bound and regulated by forkhead box protein P2 (FOXP2), a transcription factor related to speech and language development. This gene has been implicated in multiple neurodevelopmental disorders, including Gilles de la Tourette syndrome, schizophrenia, epilepsy, autism, ADHD and mental retardation.
