cargo receptor activity obsolete glycoprotein cargo receptor activity https://github.com/geneontology/go-ontology/issues/31948 true The reason for obsoletion is that this term was added in error. Most vesicle cargo are glycoproteins, so classifying cargo receptors by glycoprotein substrate introduces an additional, unhelpful axis of classification. Cargo receptor activities should instead be organized by transport domain (i.e., the vesicles they connect cargo to), with substrates captured via has_input. GO:7770028 OBSOLETE. Binding specifically to a glycoprotein (cargo) to deliver it to a transport vesicle. Glycoprotein cargo receptors span membranes, binding simultaneously to cargo molecules and coat adaptors, to efficiently recruit the cargo molecules to nascent vesicles. molecular_function
