  • Species reactivity
    Reacts with: Mouse, Rat
    Predicted to work with: Human
  • Immunogen

    Synthetic peptide conjugated to KLH derived from within residues 250 - 350 of Mouse CNTN4.

  • Positive control
    • This antibody gave a positive signal in the following tisue lysates: Mouse hippocampus; Rat olfactory bulb; Mouse E14 embryo brain; Mouse E16 embryo brain; Mouse E18 embryo brain; Mouse brain.



  • FunctionContactins mediate cell surface interactions during nervous system development. Has some neurite outgrowth-promoting activity. May be involved in synaptogenesis.
  • Tissue specificityMainly expressed in brain. Highly expressed in cerebellum and weakly expressed in corpus callosum, caudate nucleus, amygdala and spinal cord. Also expressed in testis, pancreas, thyroid, uterus, small intestine and kidney. Not expressed in skeletal muscle. Isoform 2 is weakly expressed in cerebral cortex.
  • Involvement in diseaseA chromosomal aberration involving CNTN4 has been found in a boy with characteristic physical features of 3p deletion syndrome (3PDS). Translocation t(3;10)(p26;q26). 3PDS is a rare contiguous gene disorder involving the loss of the telomeric portion of the short arm of chromosome 3 and characterized by developmental delay, growth retardation, and dysmorphic features.
  • Sequence similaritiesBelongs to the immunoglobulin superfamily. Contactin family.
    Contains 4 fibronectin type-III domains.
    Contains 6 Ig-like C2-type (immunoglobulin-like) domains.
  • Cellular localizationCell membrane. Secreted.
