Description

 Adaptor-related protein complex 3, beta 2 subunit (HGNC Symbol)

Entrez gene summary

 Adaptor protein-3 (AP3) is a heterotetrameric vesicle-coat protein complex. Some AP3 subunits are ubiquitously expressed, whereas others are expressed exclusively in neurons. The neuron-specific AP3 complex, which includes AP3B2, is thought to serve neuron-specific functions such as neurotransmitter release (Grabner et al., 2006 [PubMed 16788073]).[supplied by OMIM, Mar 2008]
