Personal communication from: Daria Hekmat-Scafe, Yale University To: Bloomington Drosophila Stock Center Subject: OS-C and OS-D location and expression Information communicated: "I noticed an error <up>in FlyBase</up> in information from our lab. OS-C and OS-D (unlike OS-E and OS-F) are NOT thought to be pheromone-binding proteins and are NOT located at 83CD. OS-C is at 84E, while OS-D is at 73F. Their expression is specific to a subset of the olfactory system, but their function is unknown."
