That’s where spider silk proteins come in. What spider silk and p53 have in common, is an unruly structure. They do entirely different things, but both types of protein are long and wobbly. Spiders keep their silk proteins this way so that they can be stored in their silk glands as a sort of dough, instead of pre-formed fibers.

Jan 31, · Spider silk is a fiber of protein, produced by a gland in the spider's abdomen. The gland stores silk protein in liquid form, which isn't particularly useful for building structures like webs. When the spider needs silk, the liquefied protein passes through a canal where it gets an acid bath. As the pH of the silk protein is lowered (as it's

Abstract. Spiders spin multiple types of silks that are renowned for their superb mechanical properties. Flagelliform silk, used in the capture spiral of an orb-web, is one of the few silks characterized by both cDNA and genomic DNA data. This fibroin is composed of repeating ensembles of three types of amino acid sequence motifs.
