Sequence Requirements of Spider Silk Elastic Proteins

Abstract

Sequence for flagelliform silk proteins from Nephila, Argiope, and Araneus species have been obtained. These sequences show significant sequence differences although the changes are not predicted to affect the secondary structure of the protein and therefore its function will be the same. Araneus shows the presence of two proteins, one a flagelliform protein and the other a major ampullate silk protein. In addition we have cloned and sequenced a number of silk proteins from glands of undetermined evolutionary origin in new spider species. We have also cloned and substantially sequenced a new protein cDNA from aciniform glands whose silk is used for prey wrapping.
