The Drosophila proteases Gastrulation Defective and Snake function in embryonic polarity establishment and bind heparin, a surrogate for anionic species present in the extracellular matrix. Here we demonstrate binding of GD, but not Snake, to anionic species that appear to be tightly associated with a highly purified eggshell matrix.

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
