Combinatorial activation and repression by seven transcription factors specify Drosophila odorant receptor expression.
The mechanism that specifies olfactory sensory neurons to express only one odorant receptor (OR) from a large repertoire is critical for odor discrimination but poorly understood.Here, we describe the first comprehensive analysis of OR expression regulation Crystal chandelier cleaner in Drosophila.A systematic, RNAi-mediated knock down of most of t
