hajureseptorigeeneillä
Hajureseptorigeenit constitute a large family of genes found in vertebrates that encode olfactory receptors. These G protein-coupled receptors are embedded in the plasma membranes of olfactory receptor neurons located in the nasal epithelium. Each olfactory receptor neuron typically expresses only one type of odorant receptor gene, allowing for the detection of specific odorant molecules. The human genome contains approximately 400 functional odorant receptor genes, a significantly smaller repertoire compared to many other mammals, suggesting a less developed sense of smell in humans.
The diversity of odorant receptor genes is crucial for the ability to discriminate between a vast array
