Anti-CRISPR (Anti-Clustered Regularly Interspaced Short Palindromic Repeats or Acr) is a group of proteins found in phages, that inhibit the normal activity of CRISPR-Cas, the immune system of certain bacteria. CRISPR consists of genomic sequences that can be found in prokaryotic organisms, that come from bacteriophages that infected the bacteria beforehand, and are used to defend the cell from further viral attacks. Anti-CRISPR results from an evolutionary process occurred in phages in order to avoid having their genomes destroyed by the prokaryotic cells that they will infect.

  • А́нти-CRISPR (англ. Anti-CRISPR) — система белков, благодаря которой бактериофаги (как бактерий, так и архей) противостоят разрушительному действию систем CRISPR/Cas. Системы анти-CRISPR описаны у многих бактериофагов. Белки этих систем в большинстве случаев мешают процессу узнавания мишени и работе белков Cas. Системы анти-CRISPR могут иметь биотехнологическое значение, поскольку могут применяться для тонкой регуляции редактирования генома с помощью технологии CRISPR/Cas9. (ru)

  • Anti-CRISPR (bahasa Inggris: Anti-Clustered Regularly Interspaced Short Palindromic Repeats atau Acr) adalah sekelompok protein yang ditemukan dalam bakteriofag (kadang hanya disebut fag), yang menghambat aktivitas normal CRISPR-Cas, sistem kekebalan bakteri tertentu. CRISPR terdiri dari urutan genom yang dapat ditemukan pada organisme prokariotik, yang berasal dari bakteriofag yang menginfeksi bakteri tersbut sebelumnya, dan digunakan untuk mempertahankan sel dari serangan virus lebih lanjut. Anti-CRISPR merupakan hasil dari proses evolusi terjadi dalam bakteriofag untuk mencegah genomnya dihancurkan oleh sel prokariotik yang akan mereka infeksi. (in)
  • As proteínas anti-CRISPR são proteínas, colectivamente denominadas proteínas AcrIIA, que inibem a capacidade do CRISPR/Cas9 comumente usado para direcionar genes específicos em outras bactérias - como E. coli - bem como em células humanas modificadas. Anti-CRISPR anula o efeito de CRISPR-Cas9 utilizando proteínas que são produzidas por vírus bacterianos. O bioquímico molecular Erik Sontheimer descreveu três proteínas em Neisseria meningitidis, bactérias que causam meningite meningocócica, que inibem sua versão de Cas9. Outros grupos também mostraram que várias estratégias artificiais - como pequenas moléculas ou luz - podem anular Cas9. A técnica tem o potencial de melhorar a segurança e a precisão das aplicações CRISPR tanto no uso clínico como na pesquisa básica. (pt)

  • Anti-CRISPR (Anti-Clustered Regularly Interspaced Short Palindromic Repeats or Acr) is a group of proteins found in phages, that inhibit the normal activity of CRISPR-Cas, the immune system of certain bacteria. CRISPR consists of genomic sequences that can be found in prokaryotic organisms, that come from bacteriophages that infected the bacteria beforehand, and are used to defend the cell from further viral attacks. Anti-CRISPR results from an evolutionary process occurred in phages in order to avoid having their genomes destroyed by the prokaryotic cells that they will infect. Before the discovery of this type of family proteins, the acquisition of mutations was the only way known that phages could use to avoid CRISPR-Cas mediated shattering, by reducing the binding affinity of the phage and CRISPR. Nonetheless, bacteria have mechanisms to retarget the mutant bacteriophage, a process that it is called "priming adaptation". So, as far as researchers currently know, anti-CRISPR is the most effective way to ensure the survival of phages throughout the infection process of bacteria. (en)

Anti-CRISPR merupakan hasil dari proses evolusi terjadi dalam bakteriofag untuk mencegah genomnya dihancurkan oleh sel prokariotik yang akan mereka infeksi. Sebelum ditemukannya protein Anti-CRISPR, mutasi merupakan satu-satunya cara yang diketahui oleh peneliti untuk menjelaskan bahwa bakteriofag dapat menghindari pemotongan yang dimediasi oleh CRISPR-Cas, yaitu dengan mengurangi afinitas pengikatan fag dan CRISPR. Meskipun demikian, bakteri memiliki mekanisme untuk menargetkan kembali bakteriofag mutan, melalui suatu proses yang disebut "priming adaptation". Sejauh yang diketahui para peneliti, anti-CRISPR merupakan cara paling efektif untuk memastikan kelangsungan hidup bakteriofag sepanjang proses infeksi bakteri. (in)
