background:
The protein encoded by this gene is a member of the immunoglobulin superfamily, and contactin family, which mediate cell surface interactions during nervous system development. This protein is a glycosylphosphatidylinositol (GPI)-anchored neuronal membrane protein that functions as a cell adhesion molecule. It may play a role in the formation of axon connections in the developing nervous system. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

Function:
CNTN5 is a member of the immunoglobulin superfamily. Contactins mediate cell surface interactions during the development of the nervous system. CNTN5 has some neurite outgrowth-promoting activity in the cerebral cortical neurons but not in hippocampal neurons and is most likely involved in neuronal activity in the auditory system.
Subcellular Location:
Cell membrane; Lipid-anchor, GPI-anchor.
Tissue Specificity:
Expressed in brain and kidney and at very low level in placenta. Not expressed in other tissues. In brain, it is highly expressed in the occipital lobe, amygdala, cerebral cortex, frontal lobe, thalamus and temporal lobe. Expressed at moderate level in the cerebellum, substantia nigra, putamen, medulla and hippocampus. Weakly expressed in the spinal cord and caudate nucleus. Weakly or not expressed in the corpus callosum.
Similarity:
Belongs to the immunoglobulin superfamily. Contactin family.
Contains 4 fibronectin type-III domains.
Contains 6 Ig-like C2-type (immunoglobulin-like) domains.
