Gene Expression + Phenotype

Homozygous inactivation of this gene results in abnormal antigen presentation via MHC class II. Mice homozygous for a knock-out allele show enhanced selection of CD4+ single positive thymocytes. Mice homozygous for a different knock-out allele show increased serum IgG1 levels.
