Olfactory marker protein directly buffers cAMP to avoid depolarization-induced silencing of olfactory receptor neurons

The physiological role of the olfactory marker protein (OMP) has been elusive. Here, the authors demonstrate that OMP buffers cAMP and modulates cAMP-gated channel activity upon sensory stimulation, maintaining neuronal firing during odour-source searching.
