Descriptions
Most SNAREs are permanently anchored to membranes, but the dually lipidated SNARE Ykt6 is found both on intracellular membranes and in the cytoplasm. The SNARE core is autoinhibited by the N-terminal longin domain. <br>The dynamics of Ykt6 are believed to be governed by the reversible palmitoylation of the protein, which cycles Ykt6 between intracellular membranes and the cytoplasm. Palmitoylation of Ykt6 increases the partition coefficient of Ykt6 to membranes, thereby shifting some populations of the protein from the cytosol to cellular membranes. Palmitoylation-mediated membrane insertion will further shift the conformational equilibrium of Ykt6 to the open state. The specific membrane localization and the amount of membrane-associated Ykt6 are predicted to be affected by its reversible palmitoylation machinery in cells, as the majority of Ykt6 exists in the unpalmitoylated cytosolic form

6 GO annotations of cellular component
| Name | Definition |
|---|---|
| cytoplasmic vesicle membrane | The lipid bilayer surrounding a cytoplasmic vesicle. |
| cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| endoplasmic reticulum | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). |
| Golgi apparatus | A membrane-bound cytoplasmic organelle of the endomembrane system that further processes the core oligosaccharides (e.g. N-glycans) added to proteins in the endoplasmic reticulum and packages them into membrane-bound vesicles. The Golgi apparatus operates at the intersection of the secretory, lysosomal, and endocytic pathways. |
| Golgi membrane | The lipid bilayer surrounding any of the compartments of the Golgi apparatus. |
| plasma membrane | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
2 GO annotations of molecular function
| Name | Definition |
|---|---|
| protein-cysteine S-palmitoyltransferase activity | Catalysis of the transfer of a palmitoyl (systematic name, hexadecanoyl) group to a sulfur atom on the cysteine of a protein molecule, in the reaction hexadecanoyl-CoA + L-cysteinyl- = CoA + S-hexadecanoyl-L-cysteinyl-. |
| SNAP receptor activity | Acting as a marker to identify a membrane and interacting selectively with one or more SNAREs on another membrane to mediate membrane fusion. |
4 GO annotations of biological process
| Name | Definition |
|---|---|
| endoplasmic reticulum to Golgi vesicle-mediated transport | The directed movement of substances from the endoplasmic reticulum (ER) to the Golgi, mediated by COP II vesicles. Small COP II coated vesicles form from the ER and then fuse directly with the cis-Golgi. Larger structures are transported along microtubules to the cis-Golgi. |
| protein transport | The directed movement of proteins into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| vesicle docking involved in exocytosis | The initial attachment of a vesicle membrane to a target membrane, mediated by proteins protruding from the membrane of the vesicle and the target membrane, that contributes to exocytosis. |
| vesicle targeting | The process in which vesicles are directed to specific destination membranes. Targeting involves coordinated interactions among cytoskeletal elements (microtubules or actin filaments), motor proteins, molecules at the vesicle membrane and target membrane surfaces, and vesicle cargo. |
