Abstract

Piriform Silk Production Most of the silk proteins originating from silk-producing glands of Nephila clavipes have been widely studied. An exception to this is Piriform silk, which originates from a relatively small gland near the spinneret. Piriform is used in the web construction process to adhere other fibers to various surfaces. Using a cDNA library generated from the Piriform gland, we seek to express the Piriform protein in E. coli. The Piriform protein itself contains two structural motifs; a PxP motif believed to contribute strength to the fiber, and a QQSSVAQS motif of unknown function. Synthetic proteins will be generated from these motifs. Production of all proteins will be scaled up in order to produce a sufficient amount for fiber-spinning studies. The synthetic proteins will then be compared to the full Piriform protein in order to elucidate the functions of the structural motifs within the entire fiber.
