AP1 adaptor complex
= AP1 adaptor complex
{c}
The <AP1 adaptor complex> is a heterotetrameric cargo-selection complex associated with <clathrin>-mediated traffic involving the <Golgi apparatus> and <endosomes>. It links membrane cargo and coat assembly at selected sites. Its role differs from that of the <AP2 adaptor complex>, which acts prominently at the plasma <cell membrane>. Adaptor identity helps determine which cargo is incorporated and where budding occurs. <Molecular Biology of the Cell, 4th edition by Bruce Alberts and others>[Chapter 13, Transport from the Trans Golgi Network to Lysosomes: clathrin adaptors]{ref}
