Protein kinase Cbeta and delta selectively phosphorylate odorant and metabotropic glutamate receptors

Chem Senses. 1999 Jun;24(3):295-9. doi: 10.1093/chemse/24.3.295.


Recombinant protein segments from a metabotropic glutamate receptor and from an odorant receptor were used as substrates in protein kinase C phosphorylation assays. Protein kinase Cbeta and delta phosphorylated an intracellular consensus phosphorylation site in the metabotropic glutamate receptor. Only protein kinase Cdelta phosphorylated a novel extracellular consensus phosphorylation site in the odorant receptor. These results suggest differential regulation of these receptors by protein kinase C isotypes.
