Mechanism by Which J Element Determines Expression of Olfactory Receptor Genes

Caption

Olfactory sensory neurons express either a class I or class II olfactory receptor gene in order to express either class I (blue) or class II (pink) olfactory sensory neurons. The enhancer is chosen based on the category, and class I sensory neurons activate one enhancer allele of the J element (green or red circle). On the other hand, class II sensory neurons activate other class II enhancers (white circle, H element is yellow or blue).
