Functioni

Component of the AP-4 complex, a novel type of clathrin- or non-clathrin-associated protein coat involved in targeting proteins from the trans-Golgi network (TGN) to the endosomal-lysosomal system. Plays a role in the intracellular trafficking of APP from the trans-Golgi network (TGN) to endosomes, and thereby inhibits amyloidogenic processing of APP (By similarity).By similarity

Interactioni

Subunit structurei

Adaptor protein complex 4 (AP-4) is a heterotetramer composed of two large adaptins (epsilon-type subunit AP4E1 and beta-type subunit AP4B1), a medium adaptin (mu-type subunit AP4M1) and a small adaptin (sigma-type AP4S1). Interacts with tyrosine-based sorting signals on the cytoplasmic tail of cargo proteins, such as LAMP2 and APP (By similarity). Interacts with the C-terminal domain of GRID2. Interacts with NAGPA.By similarity1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
