Olfactory receptor gene family

The olfactory receptor gene family consists of thousands of genes that encode proteins responsible for detecting odors. These receptors are specialized molecules located on nerve cells in the nose. When airborne molecules bind to these receptors, they send signals to the brain, allowing us to perceive different smells. Each receptor type responds to specific odor molecules, and the combination of activated receptors creates our unique sense of smell. This large gene family enables humans to detect a vast array of odors, playing a vital role in taste, environment awareness, and even emotional responses.
