Adaptor protein (AP) complexes select cargo for inclusion into clathrin coated vesicles in the late secretory and endocytic pathways. AP-1 is specific for trafficking between the trans-Golgi network and endosomes. (Adapted from PMID:10611976 and PMID:15066634).
Notes on Group
In D.mel, AP1 and AP2 share a common β subunit, AP-1-2β.
