hajureseptoriset
Hajureseptoriset refers to a class of G protein-coupled receptors (GPCRs) that are responsible for detecting odor molecules in the olfactory system. These receptors are found on the surface of olfactory sensory neurons, which are located in the nasal epithelium. When an odor molecule binds to a specific hajureseptor, it triggers a signaling cascade within the neuron. This cascade involves the activation of a G protein, which in turn activates an enzyme that produces cyclic adenosine monophosphate (cAMP). The increase in cAMP opens ion channels, leading to a change in the electrical potential of the neuron and the transmission of a signal to the brain.
The human genome encodes a large number of hajureseptoriset genes, estimated to be around 400, although not
