About us

Spider Silkome Database is a comprehensive database of amino acid / nucleotide sequence of spider silk genes (spidroins) and various properties of spider dragline silk, such as structure, morphology, thermal properties, mechanical properties and wet properties. More than 1000 spider species are covered in the database.

Spider silk has been known as a very attractive protein-based biomaterial. For example, the dragline silk has high tensile strength yet high breaking strain, and is recognized as one of the toughest natural materials.

This database was created as part of ImPACT Suzuki Project, a collaborative research project on structural proteins conducted in 2014-2018.
