Abstract excerpt
Cytoplasmic tails of LIMPII and the invariant chain contain similar leucine-based sorting signals, but the invariant chain interacts only with AP1 and AP2, whereas LIMPII interacts strongly with AP3. In a series of in vitro experiments, we investigated the effect of residues upstream of the leucine pairs and demonstrated that these residues determine adapter binding, and certain residues favor interactions with...
