This gene encodes a protein with several Transmembrane domains, a Rab11-binding domain and a lipid-binding FYVE finger domain. The encoded protein appears to promote Neurite formation. A mutation in this gene has been reported to be associated with Hereditary spastic paraplegia, however the Pathogenicity of the mutation, which may simply represent a Polymorphism (biology), is unclear.
