dc.description.abstractBarnacles can tenaciously adhere to almost any surface. To stick to a surface, glues are released and form an adhesive bond between the surface and the barnacle's base plate. The predomi-nantly proteinaceous glue is composed of approximately a dozen proteins, which serve various roles in the adhesion process. Here, protein characterization was paired with whole organism measures of adhesive strength. Barnacle adhesive strength was quantified in shear using a digital force gauge. The goal was to identify key proteins that contribute to the adhesive strength. Uncured glue from each barnacle was extracted and separated using SDS-PAGE. Abundance of each individual protein was quantified using image analysis software. Correlation analysis revealed a significant positive relationship between the abundance of a 28-kDa glue protein and adhesive strength, i.e. barnacles that expressed more of this particular protein adhered more strongly. This relationship suggests that the 28-kDa protein plays a vital role in adhesion. Subsequent analyses showed that this protein is phosphorylated with a pI of approximately 6.3. Phosphorylated proteins, which possess sticky characteristics due to negatively-charged phosphate groups, may play a role in adhesive functionality of the glue. Understanding what components and characteristics contribute to the glue's effectiveness underwater has many practical implications, including antifouling and biomedical adhesives.
