Sentences with phrase «odorant receptor genes»

The study «A long - range cis - regulatory element for class I odorant receptor genes» published in Nature Communications was a collaborative effort between Tokyo Tech, the University of Tokyo, Nihon BioData Corporation and RIKEN Brain Science Institute.

In the case of β - ionone, the smell associated with violets, McRae and colleagues managed to pinpoint the exact mutation (a change in the DNA sequence) in the odorant receptor gene OR5A1 that underlies the sensitivity to smell the compound and to perceive it as a floral note — people who are less good at smelling β - ionone also describe the smell differently, as sour or pungent, and are less likely to find it pleasant.

Each odor - detecting neuron (referred to as olfactory sensory neuron from here on), chooses a single odorant receptor gene from a fairly large number of options that are split into class I (fish - like) and class II (terrestrial - specific) odorant receptors.

Not exact matches

Zwiebel and colleagues scanned the mosquito genome looking for genes similar to those that generate fruit fly odorant receptors, proteins that project from nerve cells and initiate a biochemical cascade when they encounter certain molecules in the air.

McRae and colleagues found that the genetic variants associated all lie in or near genes that encode so - called odorant or olfactory receptors.

Christine Mißbach, first author of the study, analyzed the active genes in the insect antennae where the olfactory receptors are located and describes her discovery this way: «Astonishingly, the firebrat, which is more closely related to flying insects, employs several co-receptors, while the odorant receptors themselves are absent.»
