| Research Abstract |
We identified Niemann-Pick type C2 protein antenna-specifically expressed in worker of the Japanese carpenter ant, Camponotus japonicus. In human, this protein plays an essential role in transferring cholesterol in the cells whereas ant accumulated this protein in the basiconic sensillum and used it as a carrier protein for semiochemicals such as long-chain fatty acids, alcohols, and acetates. The protein was composed of beta-structure. The molecular mechanism of binding release was regulated by hydrogen network formation and angle change of side chain of the 112th tryptophan residue.
