longin domain; Longin-domain is N-terminal domain of a subgroup of R-SNARE proteins, including VAMP7, Ykt6, and Sec22. Longin is one of the approximately 26 components required for transporting proteins from the ER to the plasma membrane, via the Golgi apparatus. It is necessary for the steps of the transfer from the ER to the Golgi complex. Longins are the only R-SNAREs that are common to all eukaryotes, and they are characterized by a conserved N-terminal domain with a profilin-like fold called a longin domain.

SNARE motif; SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins consist of coiled-coil helices (called SNARE motifs) which mediate the interactions between SNARE proteins, and a transmembrane domain. The SNARE complex mediates membrane fusion, important for trafficking of newly synthesized proteins, recycling of pre-existing proteins and organelle formation. SNARE proteins are classified into four groups, Qa-, Qb-, Qc- and R-SNAREs, depending on whether the residue in the hydrophilic center layer of the four-helical bundle is a glutamine (Q) or arginine (R). Qa-, Qb- and Qc-SNAREs are localized to target organelle membranes, while R-SNARE is localized to vesicle membranes. They form unique complexes consisting of one member of each subgroup, that mediate fusion between a specific type of vesicles and their target organelle. Their SNARE motifs form twisted and parallel heterotetrameric helix bundles.

SNARE motif of VAMP7; The VAMP-7 (vesicle-associated membrane protein 7, also called synaptobrevin-like protein 1) protein belongs to the R-SNARE subgroup of SNAREs and interacts with syntaxin 7(Qa), syntaxin 8 (Qc) and Vti1b (Qb). The complex is involved in the transport from early endosomes to the lysosome via regulating the transport from multivesicular bodies to the lysosomes. SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins contain coiled-coil helices (called SNARE motifs) which mediate the interactions between SNARE proteins, and a transmembrane domain. The SNARE complex mediates membrane fusion, important for trafficking of newly synthesized proteins, recycling of pre-existing proteins and organelle formation.

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).
