Olfactory receptor 56A4 (OR56A4)

Olfactory receptor 56A4 (OR56A4) is a member of the olfactory receptor family, a large group of G protein-coupled receptors (GPCRs) responsible for detecting odorant molecules in the nasal epithelium, leading to perception of smell[2][5]. These receptors have a characteristic seven-transmembrane domain structure and function through G protein-mediated signal transduction, with binding of specific ligands (such as decanal and undecanal) triggering neuronal responses[2][3][5]. The OR56A4 gene is protein-coding and is not a pseudogene[4]. While primarily associated with olfactory function, there is limited data linking this gene to disease (e.g., Gait Apraxia)[5].
