MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a subunit of the heterotetrameric adaptor-related protein comlex 1 (AP-1), which belongs to the adaptor complexes medium subunits family. This protein is capable of interacting with tyrosine-based sorting signals. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]
PHENOTYPE: Homozygous null mice show small intestine crypt hyperplasia and villous dysplasia due to altered polarity and hyperproliferation of epithelial cells, exhibit spontaneous chronic colitis due to epithelial immune dysfunction, and develop a digestive disorder that causes malnutrition, growth retardation and early death.
