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
2017].
