  • Title: Smelly feet are not always a bad thing: the relationship between cyprid footprint protein and the barnacle settlement pheromone.
    Author: Dreanno C, Kirby RR, Clare AS.
    Journal: Biol Lett; 2006 Sep 22; 2(3):423-5. PubMed ID: 17148421.
    Abstract:
    A critical phase in the life cycle of sessile benthic marine invertebrates is locating a suitable substratum for settlement. For barnacles, it is the lecithotrophic cypris larva that makes this plankto-benthic transition. In exploring possible substrata for settlement, the cyprid leaves behind 'footprints' of a proteinaceous secretion that reportedly functions as a temporary adhesive, and also acts as a secondary cue in larval-larval interactions at settlement. Here, we show that two polyclonal antibodies raised against peptides localized at the N- and C-terminal regions of the adult settlement cue--the settlement-inducing protein complex (SIPC)--could both detect 'temporary adhesive' indicating that the SIPC is either a component of this secretion or that they are the same protein.
