It is a highly expressed, cytoplasmic protein found in mature olfactory sensory receptor neurons of all vertebrates.
OMP is a modulator of the olfactory signal transduction cascade.
The crystal structure of OMP reveals a beta sandwich consisting of eight strands in two sheets with a jelly-roll topology.
[1] Three highly conserved regions have been identified as possible protein–protein interaction sites in OMP, indicating a possible role for OMP in modulating such interactions, thereby acting as a molecular switch.
