MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein with an arfaptin homology domain that is found both in the cytosol and as membrane-bound form on the Golgi complex and immature secretory granules. This protein is believed to be an autoantigen in insulin-dependent diabetes mellitus and primary Sjogren's syndrome. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Feb 2013]
PHENOTYPE: Homozygous mutation of this gene results in diabetes and spontaneous lethality at 4-5 months of age on a NOD background, however mice on a 129/Sv background are normal. Onset of diabetes starts 4 weeks later than wild-type NOD mice and mutants are resistant to cyclophospamide-accelerated diabetes. [provided by MGI curators]
