AP-3 complex subunit sigma; AP-3 complex sigma 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 sigma subunit is comprised of a single longin domain and plays a role in binding dileucine-based sorting signals.

AP complex subunit sigma; AP complex sigma subunits are part of the heterotetrameric adaptor protein (AP) complex which consists of one large subunit (alpha-, gamma-, delta- or epsilon), one beta-, one mu-, and one sigma-subunit. 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 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-4 does not bind the coat protein clathrin, it is associated with nonclathrin coats. Its phospholipid binding partner is unknown and it is localized in the trans-Golgi network (TGN). The sigma subunit is comprised of a single longin domain and plays a role in binding dileucine-based sorting signals.

zeta subunit of the F-COPI complex; Zeta subunit of the heterotetrameric F-COPI complex, which consists of one beta-, one gamma-, one delta-, and one zeta subunit, where beta- and gamma- subunits are related to the large adaptor protein (AP) complex subunits, and delta- and zeta- subunits are related to the medium and small AP subunits, respectively. F-COPI forms a coatomer together with the B-COPI subcomplex, which assembles with a small GTPase, ADP-ribosylation factor 1 (ARF1), playing an important role in the formation of COPI complex-coated vesicles. COPI complex-coated vesicles function in the early secretory pathway mediating the retrograde transport from the Golgi to the ER, and intra-Golgi transport.
