Easel 11: Identification and biochemical analysis of proteins in cobweb weaving spiders’ gumfoot glue droplets

Sign up or log in to save this to your schedule and see who's attending!

Spider aggregate gland secretions perform a host of different function among different groups of spiders. In cobweb weaving spiders, aggregate secretions are involved in formation of gumfoot lines. These gumfoot lines function to capture and catapult walking prey into the main web with adhesion to gumfoot glue droplets and catapulting through a spring-like action of the lines. Currently, the proteins comprising the gumfoot glue droplets are unknown, and we are working to identify these proteins using biochemical and spectroscopic methods. Identification of these proteins would provide a beneficial insight into the evolution of spider silk glands, as well as provide a unique perspective on possible biosynthetic glues that could be manufactured from aggregate secretions.
