Analysis of the antifreeze glycoprotein containing genomic locus in the Antarctic notothenioid fish dissostichus mawsoni
… radiation was linked to the evolution of antifreeze glycoproteins (AFGPs). High blood levels of AFGPs (25 to 35 mg/ml) lower their freezing point a few tenths of a degree below that of seawater (-1.86oC) and are a vital part of their freeze avoidance strategy. The AFGP gene evolved from a …

Creating sense from non-sense DNA: de novo genesis and evolutionary history of antifreeze glycoprotein gene in northern cod fishes (gadidae)
… Seven gadid species are known to have evolved antifreeze glycoproteins (AFGPs) that enable their survival from inoculative freezing by environmental ice in frigid Arctic and sub-Arctic waters. AFGPs protect the fish from freezing death by binding to ice crystals and arresting ice growth within …

Comparative antifreeze trait analyses of Antarctic and temperate sister species pairs shed light on tempo of adaptive trait loss under relaxed selection
… Southern Ocean survive by having evolved antifreeze glycoproteins (AFGP). Over evolutionary time several lineages have escaped the isolated frigid Southern Ocean to north of the Antarctic Polar Front and successfully colonized temperate sub-Antarctic waters. This study investigates the …

Behavioral freeze avoidance in an Antarctic fish
… primarily by the action of their blood-borne antifreeze glycoproteins (AFGPs). AFGPs arrest the growth of environmental ice crystals that enter the fish, thereby preserving the body fluids in liquid state. AFGPs are ubiquitous in all adult Antarctic notothenioids examined, except for an early …
