COMMENT     REVIEWED REFSEQ: This record has been curated by NCBI staff. The
            reference sequence was derived from AC105339.9 and FJ695193.1.
            This sequence is a reference standard in the RefSeqGene project.
            
            Summary: 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
