Protein Classification

coatomer subunit zeta( domain architecture ID 13000590)

coatomer subunit zeta is a component of the coatomer, a cytosolic protein complex that binds to dilysine motifs and reversibly associates with Golgi non-clathrin-coated vesicles, which further mediate biosynthetic protein transport from the ER, via the Golgi up to the trans Golgi network

 47-178 3.91e-74

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.

Longin-like domains of AP complex subunits; 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.

Longin-like domains; Longin-like domains are small protein domains present in a variety of proteins and members of protein complexes involved in or required for different steps during the transport of proteins from the ribosome to the ER to the plasma membrane, via the Golgi apparatus. Examples are mu and sigma subunits of the heterotetrameric adaptor protein (AP) complex, zeta and delta subunits of the heterotetrameric F-COPI complex, a subgroup of R-SNARE proteins, a subfamily of the transport protein particle (TRAPP), and the signal recognition particle receptor subunit alpha (SR-alpha).

AP-4 complex subunit sigma; AP-4 complex sigma subunit is part of the heterotetrameric adaptor protein (AP)-1 complex which consists of one large epsilon-, 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-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.

AP-2 complex subunit mu N-terminal domain; AP-2 complex mu subunit is part of the heterotetrameric adaptor protein (AP)-2 complex which consists of one large alpha-, 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-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. 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.
