OR56B1

OR56B1 is a gene that encodes a protein in the olfactory receptor family. This family is responsible for the detection of odor molecules, and the encoded protein is thought to play a role in the olfactory system of the nasal cavity.

Function

The olfactory system is a sensory system used for smelling (and sometimes tasting). Most mammals have a main olfactory system and an accessory olfactory system. The main olfactory system detects airborne substances, while the accessory system is specialized to detect fluid-phase stimuli. The olfactory receptor proteins, such as OR56B1, are integral membrane proteins that bind odorant molecules in the nose and initiate a neural response that triggers the perception of a smell.

Gene

The OR56B1 gene is located on the short (p) arm of chromosome 11 at position 15.4. More precisely, the OR56B1 gene is located from base pair 20,235,769 to base pair 20,236,769 on chromosome 11.

Clinical significance

Mutations in the OR56B1 gene have been associated with a reduced ability to smell, a condition known as anosmia. Further research is needed to fully understand the clinical implications of this gene.
