AP-3 is a heterotetrameric adaptor involved in the biogenesis of lysosome-related organelles. The function of AP-3 as an adaptor relies on its ability to bind to membranes in an Arf-dependent fashion and to recognize sorting signals in the cytosolic tails of the transmembrane cargo. Here, we report an interdomain interaction involving the ear domain of the delta subunit and the sigma3 subunit of AP-3. This interaction interferes with the binding of AP-3 to Arf but not to dileucine-based sorting… CONTINUE READING
