CNTN4
Introduction
Contactin 4, also known as CNTN4, is a human gene.[1]
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. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined.[1]
Abnormal expression of this gene has been implicated in some cases of autism. [2]
