MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the NF-kappa-B inhibitor family, which contain multiple ankrin repeat domains. The encoded protein interacts with REL dimers to inhibit NF-kappa-B/REL complexes which are involved in inflammatory responses. The encoded protein moves between the cytoplasm and the nucleus via a nuclear localization signal and CRM1-mediated nuclear export. Mutations in this gene have been found in ectodermal dysplasia anhidrotic with T-cell immunodeficiency autosomal dominant disease. [provided by RefSeq, Aug 2011]
PHENOTYPE: Mice homozygous for disruptions in this gene die at about 1 week of age experiencing abnormalities in the immune system. Mice homozygous for an allele disrupting the N-terminal nuclear export signal exhibit impaired B cell maturation, decreased CD4+ memory T cells, and decreased regulatory T cells.
