Identification of cytoskeletal proteins in the antennae of the silkmoths Antheraea polyphemus and A. pernyi.
Although the overall cytoskeletal morphology of the olfactory dendrite in the antennae of the silkmoths Antheraea polyphemus and A. pernyi is known, the cytoskeleton proteins that structurally and functionally support these structures remain to be identified in this paper, we describe the identification of tubulin, actin and intermediate filament-like proteins in the olfactory dendrites, and motor proteins such as kinesin and unconventional myosin in the antennal branches by the use of antibodies. We also show that the tubulins within the olfactory dendrites and in the antennal branches are acetylated. This study provides valuable information concerning the possible role of these proteins in transduction, transport and motility, as is evident in other systems.
