Olfactory receptor gene repertoires in mammals.
In mammals, olfaction is mediated by two distinct organs that are located in the nasal cavity: the main olfactory epithelium (MOE) that binds volatile odorants is responsible for the conscious perception of odors, and the vomeronasal organ (VNO) that binds pheromones is responsible for various behavioral and neuroendocrine responses between individuals of a same species. Odorants and pheromones...
متن کاملSimilar numbers but different repertoires of olfactory receptor genes in humans and chimpanzees.
Animals recognize their external world through the detection of tens of thousands of chemical odorants. Olfactory receptor (OR) genes encode proteins for detecting odorant molecules and form the largest multigene family in mammals. It is known that humans have fewer OR genes and a higher fraction of OR pseudogenes than mice or dogs. To investigate whether these features are human specific or co...
متن کاملA comparison of the human and chimpanzee olfactory receptor gene repertoires.
Olfactory receptor (OR) genes constitute the basis of the sense of smell and are encoded by the largest mammalian gene superfamily, with >1000 members. In humans, but not in mice or dogs, the majority of OR genes have become pseudogenes, suggesting that OR genes in humans evolve under different selection pressures than in other mammals. To explore this further, we compare the OR gene repertoire...
متن کاملSingular Expression of Olfactory Receptor Genes
Understanding the mechanisms of monogenic and monoallelic transcription of the large repertoire of olfactory receptor genes represents a challenging task. A picture is now emerging in which odorant receptor choice and stabilization involve an escape from silencing followed by the activation of an unconventional feedback loop.
متن کاملPromoter architecture of mouse olfactory receptor genes.
Odorous chemicals are detected by the mouse main olfactory epithelium (MOE) by about 1100 types of olfactory receptors (OR) expressed by olfactory sensory neurons (OSNs). Each mature OSN is thought to express only one allele of a single OR gene. Major impediments to understand the transcriptional control of OR gene expression are the lack of a proper characterization of OR transcription start s...
