obsolete vesicle tethering to endoplasmic reticulum https://github.com/geneontology/go-ontology/issues/31868 true tb 2013-01-08T15:07:50Z biological_process This term was obsoleted because it represents a molecular function rather than a biological process. Annotations should be reviewed; the VAP-related proteins previously annotated here are lipid transfer/adaptor proteins rather than vesicle tethers, and other types of membrane adaptor terms may be more appropriate. Where the activity is genuinely vesicle tethering, reannotate to GO:7770062 'vesicle membrane tethering activity'. GO:0099044 OBSOLETE. The initial, indirect interaction between a transport vesicle membrane and the membrane of the endoplasmic reticulum. 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 fusion. vesicle membrane tethering activity
