Contactin 1, also known as CNTN1, is a protein which in humans is encoded by the CNTN1 gene.^[5][6]

Function

The protein encoded by this gene is a member of the immunoglobulin superfamily. It 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. Two alternatively spliced transcript variants encoding different isoforms have been described for this gene.^[6]

Interactions

CNTN1 has been shown to interact with PTPRB.^[7][8]
