Identification of recombinant settlement-inducing protein complex from Amphibalanus amphitrite by LC-MS/MS


ABSTRACT: Settlement-inducing protein complex (SIPC) is a protein that acts as a phoromone cue to attract conspecific of the barnacle Amphibalanus amphitrite to settle on a substrate. Recombinant settlement-inducing protein complex was expressed in insect Sf9 cells through a baculovirus overexpression system, purified and analysed by mass spectrometry to confirm its identity.

Reproduction in barnacles relies on chemical cues that guide their gregarious settlement. These cues have been pinned down to several sources of settlement pheromones, one of which is a protein termed settlement-inducing protein complex (SIPC), a large glycoprotein acting as a pheromone to induce larval settlement and as an adhesive in surface exploration by the cyprids. Settlement assays in laboratory conditions with <i>Amphibalanus</i> (=<i>Balanus</i>) <i>amphitrite</i> cyprids in the presenc  ...[more]
