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.[7]

Genomics

The gene is located on the short arm of chromosome 3 (3p26.3). It is a single copy gene within the Watson (plus) strand, 957,399 bases in length and encodes a protein of 1026 amino acids (molecular weight 113.454 kDa)

Clinical relevance

Abnormal expression of this gene has been implicated in some cases of autism.[8] It has also been associated with cerebellar degeneration in spinocerebellar ataxia type 16.
