Antifreeze proteins (AFPs) or ice structuring proteins refer to a class of polypeptides produced by certain animals, plants, fungi and bacteria that permit their survival in temperatures below the freezing point of water. AFPs bind to small ice crystals to inhibit the growth and recrystallization of ice that would otherwise be fatal. There is also increasing evidence that AFPs interact with mammalian cell membranes to protect them from cold damage. This work suggests the involvement of AFPs in cold acclimatization.

  • Les Proteïnes antigel o proteïnes anticongelants (PA, i les sigles en anglès AFP) són un tipus de polipèptids produït per certs animals vertebrats, plantes fongs i bacteris que els premeten sobreviure n ambients per sota dels 0 °C. Aquestes proteïnes s'uneixen a petits cristalls de gel per inhibir el creixement (cristal·logènesi) i la recristal·lització del gel que d'altra manera els seria fatal. S'ha suggerit que aquestes proteïnes intervenen en l' al fred dels organismres. (ca)

  • Anti-Frost-Proteine (AFP), auch Eisstrukturierende Proteine (englisch ice-structuring proteins, ISP), Frostschutzproteine oder thermale Hystereseproteine (THP) sind eine Klasse von Proteinen, die von bestimmten Wirbeltieren, Pflanzen, Pilzen und Bakterien gebildet werden, um in einer Umgebung mit Temperaturen unter dem Gefrierpunkt von Wasser zu überleben.

  • Les protéines antigel correspondent à une classe de polypeptides naturellement produites par certaines espèces de vertébrés à sang froid, de plantes, de fungis et de bactéries et qui leur permettent d'être congelés sans mourir et/ou de vivre activement dans des environnements très froids (jusqu'à des températures inférieures à 0 °C, dans l'eau de mer par exemple). Elles sont souvent nommées AFPs (de l'anglais : Antifreeze proteins). (fr)
  • Le proteine antigelo (Antifreeze proteins, AFP) o proteine strutturanti il ghiaccio (Ice structuring proteins, ISP) sono una classe di polipeptidi prodotti da alcuni vertebrati, piante, funghi e batteri che permettono la loro sopravvivenza in ambienti sottozero. Queste proteine si legano ai piccoli cristalli di ghiaccio e ne impediscono la crescita e ricristallizzazione, che altrimenti sarebbe fatale. Vi è inoltre una crescente evidenza che le AFP interagiscono con le membrane cellulari delle cellule di mammifero per proteggerli dai danni da freddo. (it)
  • 不凍タンパク質(ふとうタンパクしつ、英: Antifreeze protein, AFP)は、生体において、主に生体の凍結防止や氷の再結晶防止による生物の生命維持に寄与するタンパク質のこと。耐凍タンパク質ともよばれ、近年では氷構造(化)タンパク質 (ice structuring proteins, ISPs) ともよばれることがある。 数グループが存在し、また糖との結合体である不凍糖タンパク質などの誘導体が存在する。そのため、これらをまとめて「不凍タンパク質類」(AFPs) と呼称することもある。 (ja)

  • 不凍蛋白質(抗凍蛋白)(Antifreeze proteins ,AFPs)或叫冰結構蛋白(ice structuring proteins ,ISPs)是指一類由某些脊椎動物、植物、真菌和細菌產生的多肽。這些多肽能保證這些物種在零下溫度環境下生存。AFP結合到小的冰晶上,阻止冰的結晶化和晶體的生長,不然,將會對那些生命物種是致命的。越來越多的證據表明,AFP與哺乳動物細胞膜相互作用保護細胞膜不會被凍壞。關于不凍蛋白的研究提示ATF參與生物體對冷氣候的適應過程。 (zh)
