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.

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 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.
