MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Adaptor protein complex 3 (AP-3 complex) is a heterotrimeric protein complex involved in the formation of clathrin-coated synaptic vesicles. The protein encoded by this gene represents the beta subunit of the neuron-specific AP-3 complex and was first identified as the target antigen in human paraneoplastic neurologic disorders. The encoded subunit binds clathrin and is phosphorylated by a casein kinase-like protein, which mediates synaptic vesicle coat assembly. Defects in this gene are a cause of early-onset epileptic encephalopathy. [provided by RefSeq, Feb 2017]
PHENOTYPE: Disruption does not alter pigmentation, but causes hyperactivity and tonic-clonic seizures and mice homozygous for a knock-out allele were found to have significantly reduced synaptic zinc levels throughout the brain, with the largest reduction observed in the CA1 stratum oriens. [provided by MGI curators]
