This gene encodes a member of the ALEX family of proteins
which may play a role in tumor suppression. The encoded protein
contains a potential N-terminal transmembrane domain and a single
Armadillo (arm) repeat. Other proteins containing the arm repeat
are involved in development, maintenance of tissue integrity, and
tumorigenesis. This gene is closely localized with other family
members on the X chromosome. Three transcript variants encoding the
same protein have been identified for this gene. [provided by
