Abstract: | "Antennal proteins of the male fire ant (Solenopsis invicta) were analyzed by two-dimensional gel electrophoresis, with the objective of identifying pheromone-binding proteins, which have not previously been found in ant antennae. The major low-molecular weight protein found in the male fire ant antenna was subjected to Edman degradation to determine the N-terminal amino acid sequence. Degenerate PCR primers based on this sequence were used to obtain a cDNA sequence corresponding to the full-length protein sequence. In-gel trypsin digestion followed by MALDI-TOF mass spectrometry and HPLC-ESI/MS/MS demonstrated that the protein gel spot contained only the protein corresponding to the cDNA sequence obtained by PCR. The sequence is similar to apolipophorin-III, an exchangeable lipid-binding protein. Fire ant apolipophorin-III is expressed in the antenna as well as the head, thorax and abdomen" |
