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 3 (AP-3), which belongs to the adaptor complexes medium subunits family. The AP-3 complex plays a role in protein trafficking to lysosomes and specialized organelles. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Aug 2008]
PHENOTYPE: Homozygous null mice suffer from spontaneous recurrent epileptic seizures, are more susceptible to drug-induced seizures and show impaired GABA release, fewer synaptic vesicles, enhanced long-term potentiation, and abnormal propagation of neuronal excitability via the temporoammonic pathway.
