AP-1 complex subunit sigma; AP-1 complex sigma subunit is part of the heterotetrameric adaptor protein (AP)-1 complex which consists of one large gamma-, one beta-, one mu-, and one sigma-subunit. AP complexes link the cytosolic domains of the cargo proteins to the protein coat that induces vesicle budding in the donor compartment during vesicle transport. In the case of AP-1 the coat protein is clathrin. AP-1 binds the phospholipid PI(4)P which plays a role in its localisation to the trans-Golgi network (TGN)/endosome. The sigma subunit is comprised of a single longin domain and plays a role in binding dileucine-based sorting signals.

AP complexes link the cytosolic domains of the cargo proteins to the protein coat that induces vesicle budding in the donor compartment during vesicle transport. In the case of AP-2 the coat protein is clathrin. AP-2 binds the phospholipid PI(4,5)P2 which is important for its localisation to the plasma membrane.

In general, AP complexes link the cytosolic domains of the cargo proteins to the protein coat that induces vesicle budding in the donor compartment during vesicle transport. In most cases the coat protein is clathrin (AP1 and AP2 complex), but some of the other members of the AP complex family are associated with nonclathrin coats. The sigma subunit is comprised of a single longin domain and plays a role in binding dileucine-based sorting signals.

AP-3 complex subunit mu N-terminal domain; AP-3 complex mu subunit is part of the heterotetrameric adaptor protein (AP)-1 complex which consists of one large delta-, one beta-, one mu-, and one sigma-subunit. AP complexes link the cytosolic domains of the cargo proteins to the protein coat that induces vesicle budding in the donor compartment during vesicle transport. AP-3 binds the coat protein clathrin and the phospholipid PI(3)P and it is localized in the endosome. The mu subunit is comprised of an N-terminal longin domain followed by a C-terminal domain which is involved in the binding of the Y-X-X-Phi sorting signal.
