Evolution of an antifreeze glycoprotein.

Résumé

The ice-binding anti-freeze glycoprotein (AFGP) that circulates in the blood of Antarctic notothenioid fishes enables them to avoid freezing in their perpetually icy environment. This crucial survival protein probably arose from a functionally unrelated pancreatic trypsinogen-like protease. The authors have discovered an important intermediate in this evolutionary process: transcriptionally active chimaeric genes that encode both an AFGP polyprotein and the protease, confirming the protease origin of AFGP and indicating how it was created.
