Accessory protein determines whether pheromones are detected

Pheromones are like the molecules you taste as you chomp on a greasy french fry: big and fatty. In research to be published in the October 17 advance online issue of Nature, Rockefeller University researchers reveal an unanticipated role for a new CD36-like protein to help cells detect these invisible communication signals that drive a wide range of behaviors, from recognizing a sibling to courting a mate, a finding that may explain what pheromone communication, pathogen recognition and fat taste perception all have in common.
