Functional Analysis of Human D1 and D5 Dopaminergic G Protein-Coupled Receptors: Lessons from Mutagenesis of a Conserved Serine Residue in the Cytosolic End of Transmembrane Region 6
The external part of the transmembrane region of HA (haemagglutinin) of influenza virus contains a cholesterol consensus motif originally identified in G-protein-coupled receptors. Various mutations in this motif retard transport of HA through the Golgi and reduce raft association.
