Adaptin

Adaptin (AP) are proteins which mediate the formation of vescicles by clathrin-coated pits. The AP-2 complex is a heterotetramer composed of 2 large AP: AP-α or AP-γ and AP-β, a medium-size AP: AP-μ and small AP: AP-σ. AP complexes connect proteins and lipids to clathrin budding sites. There are different AP complexes in mammals.^[1]
