  • adj. Of or pertaining to the perciform suborder Notothenioidei, the Antarctic icefish.


Sorry, no etymologies found.


  • Thirty-five years ago Arthur DeVries of the University of Illinois at Urbana-Champaign first documented antifreeze glycoproteins (AFGPs) in Antarctic notothenioid fishes.

  • In trillions of Antarctic notothenioid fish in the past ten million years, no new regulatory regions seem to have helped much in the fight against freezing water—only changes in protein sequences do.

    The Edge of Evolution

  • On the one hand, there are the notothenioid fish in the Antarctic region, which can survive temperatures that should freeze their blood solid.

    The Edge of Evolution

  • The reason is that the gene for a pigmentation protein called Yellow protein which actually produces dark pigmentation has gained a new switch sequence for a particular regulatory protein.42 This result is important because it shows random mutation not only breaks switches, but occasionally makes new ones, too, just as it occasionally makes proteins with new functions such as the antifreeze protein of notothenioid fish.

    The Edge of Evolution

  • Evolution of antifreeze glycoprotein gene from a trypsinogen gene in Antarctic notothenioid fish.

    The Edge of Evolution

  • A remarkable twist to this conventional gene-duplication/sequence-divergence paradigm is the creation of a unique functional antifreeze glycoprotein (AFGP) sequence from partly non-coding DNA in Antarctic notothenioid fish, involving de novo duplications of a 9-nt sequence spanning an exon-intron junction of an ancestral trypsinogen-type protease gene to form a large, highly repetitive (ThrAlaAla)n coding region, and shedding most of the protease gene structure.

  • Chen et al. demonstrate that an Antifreeze Glycoprotein AFGP gene from the Antarctic notothenioid Dissostichus mawsoni derives from a gene encoding a pancreatic trypsinogen.

  • The study, in the Proceedings of the National Academy of Sciences, is the first to search the genome of an Antarctic notothenioid fish for clues to its astounding hardiness.
