vesicle transport through interaction with t-SNAREs homolog 1B [Homo sapiens]

Protein Classification

SNARE domain-containing protein; syntaxin family protein( domain architecture ID 10523357)

SNARE domain-containing protein such as SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins, which interact to form a SNARE complex that mediates membrane fusion, important for trafficking of newly synthesized proteins, recycling of pre-existing proteins and organelle formation; syntaxin family protein similar to syntaxin 5 (Syn5) that regulates the transport from the ER to the Golgi, as well as the early/recycling endosomes to the trans-Golgi network and participates in the assembly of transitional ER and the Golgi, lipid droplet fusion, and cytokinesis

136-197 6.72e-24

SNARE motif of Vti1b-like; Vti1b (vesicle transport through interaction with t-SNAREs homolog 1B) belongs to the Qb subgroup of SNAREs (soluble N-ethylmaleimide-sensitive factor attachment protein receptor). Vti1b interacts with syntaxin 7 (Qa), syntaxin 8 (Qc), and the lysosomal R-SNARE VAMP8 or VAMP7 to form the endosomal SNARE core complexes that mediate transport from the early endosomes and the MVBs (multivesicular bodies), and from the MVBs to the lysosomes, respectively. SNARE 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-, as well as 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. Examples for members of the Qb SNAREs are N-terminal domains of SNAP23 and SNAP25, Vti1, Sec20 and GS27.

N-terminal SNARE motif of SNAP29; N-terminal SNARE motif of SNAP29, a member of the Qb/Qc subfamily of SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins. SNAP29 interacts with STX17 (Qa) and the lysosomal R-SNARE VAMP8. The complex plays a role in autophagosome-lysosome fusion. Autophagosome transports cytoplasmic materials including cytoplasmic proteins, glycogen, lipids, organelles, and invading bacteria to the lysosome for degradation. Qb/Qc SNAREs consist of 2 coiled-coil helices (called SNARE motifs, one belonging to the Qb subgroup and one belonging to the Qc subgroup), which mediate the interactions with other SNARE proteins, and a transmembrane domain. In general, 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-, as well as 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. Other members of the Qb/Qc SNAREs are SNAP23, SNAP25, SNAP47 and SEC9.

SNARE motif of SYN8; Fungal SYN8 is a member of the Qc subfamily of SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) protein family presetn in the endosomes. SNARE 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).
