Abstract
The presence in cypress pollen of an important allergen, belonging to the gibberellin-regulated protein (GRP) family, has been suggested for many years. However, it has never been isolated and sometimes the homologous peach allergen, Pru p 7, has been used as a surrogate to perform immunological investigations. The aim of this study has been the isolation and molecular characterization of the GRP contained in the Cupressus sempervirens pollen. This protein, named Cypmaclein, has been purified from the natural source using conventional biochemical methods consisting in different chromatographic separations. Cypmaclein has been identified by direct protein sequencing of the N-terminal region and of internal fragments of the molecule. In SDS-PAGE, its apparent molecular mass is slightly higher than that of Pru p 7. Nevertheless, the mass spectrometry experiments reveal that the exact molecular mass of Cypmaclein (6821.88 Da) is very close to that of Pru p 7 (6909.90 Da). Two regions of Cypmaclein have been sequenced providing 50% of its primary structure. A high overall sequence identity of Cypmaclein with all the analyzed GRP has been observed, although in the N-terminal region the high identity is limited to the homolog of Crypt...Continue Reading
