obsolete vesicle tethering https://github.com/geneontology/go-ontology/issues/31881 true This term was obsoleted because it represents a molecular function (vesicle membrane tethering activity) rather than a biological process. Annotations should be reviewed and reannotated to the new MF term GO:7770062 'vesicle membrane tethering activity', and where appropriate combined with the relevant vesicle-mediated transport / exocytosis process term in a GO-CAM model. OBSOLETE. The initial, indirect interaction between a vesicle membrane and a membrane to which it is targeted for fusion. This interaction is mediated by tethering factors (or complexes), which interact with both membranes. Interaction can occur via direct binding to membrane phospholipids or membrane proteins, or via binding to vesicle coat proteins. This process is distinct from and prior to interaction between factors involved in fusion. biological_process GO:0099022 vesicle membrane tethering activity
