Abstract: | "Two proteins of the IP3 transduction pathway were identified by Western blots in homogenates of isolated pheromone-sensitive sensilla of the silkmoth Antheraea polyphemus. A 110 kDa protein was recognized by an antiserum raised against the Drosophila phospholipase C beta (PLC beta p121) and a 80kDa protein was labelled by an antiserum against a synthetic peptide of a conserved region of protein kinase C (PKC). Incubation of homogenized sensory hairs with the main sex pheromone component, (E,Z) 6-11 hexadecadienyl acetate, resulted in a 6-fold increase in the activity of PKC compared to controls without pheromone. In contrast, incubation with pheromone did not affect the activity of protein kinase A (PKA). Activation of PKC by the membrane permeable dioctanoylglycerol led to excitation of the pheromone-sensitive receptor neurons. These data support the current concept that pheromone perception of moths is mediated by the IP3 transduction pathway" |
