  2. Cas9 - Wikipedia

    en.wikipedia.org/wiki/Cas9

    IPR028629. Cas9 (CRISPR associated protein 9, formerly called Cas5, Csn1, or Csx12) is a 160 kilodalton protein which plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids, and is heavily utilized in genetic engineering applications. Its main function is to cut DNA and thereby alter a cell's genome.

  3. CRISPR gene editing - Wikipedia

    en.wikipedia.org/wiki/CRISPR_gene_editing

    CRISPR-Cas9 genome editing techniques have many potential applications. The use of the CRISPR-Cas9-gRNA complex for genome editing [10] was the AAAS's choice for Breakthrough of the Year in 2015. [11] Many bioethical concerns have been raised about the prospect of using CRISPR for germline editing, especially in human embryos. [12]

  4. CRISPR - Wikipedia

    en.wikipedia.org/wiki/CRISPR

    Double-strand DNA breaks introduced by CRISPR-Cas9 allows further genetic manipulation by exploiting endogenous DNA repair mechanisms. CRISPR-Cas immunity is a natural process of bacteria and archaea. [103] CRISPR-Cas prevents bacteriophage infection, conjugation and natural transformation by degrading foreign nucleic acids that enter the cell ...

  5. CRISPR activation - Wikipedia

    en.wikipedia.org/wiki/CRISPR_activation

    CRISPR activation (CRISPRa) is a gene regulation technique that utilizes an engineered form of the CRISPR-Cas9 system to enhance the expression of specific genes without altering the underlying DNA sequence. Unlike traditional CRISPR-Cas9, which introduces double-strand breaks to edit genes, CRISPRa employs a modified, catalytically inactive ...

  6. Protospacer adjacent motif - Wikipedia

    en.wikipedia.org/wiki/Protospacer_adjacent_motif

    PAM and size of various CRISPR DNA nucleases . The canonical PAM is the sequence 5'-NGG-3', where "N" is any nucleobase followed by two guanine ("G") nucleobases. [9] Guide RNAs can transport Cas9 to any locus in the genome for gene editing, but no editing can occur at any site other than one at which Cas9 recognizes PAM.

  7. Genome-wide CRISPR-Cas9 knockout screens - Wikipedia

    en.wikipedia.org/wiki/Genome-wide_CRISPR-Cas9...

    The clustered regularly interspaced short palindrome repeats (CRISPR)/Cas9 system is a gene-editing technology that can introduce double-strand breaks (DSBs) at a target genomic locus. By using a single guide RNA (sgRNA), the endonuclease Cas9 can be delivered to a specific DNA sequence where it cleaves the nucleotide chain. [28]

  8. Guide RNA - Wikipedia

    en.wikipedia.org/wiki/Guide_RNA

    The cas9 complex, illustrating the gRNA, PAM and the double-stranded break induced in the target DNA. CRISPR (Clustered regularly interspaced short palindromic repeats)/Cas9 is a technique used for gene editing and gene therapy. Cas is an endonuclease enzyme that cuts DNA at a specific location directed by a guide RNA.

  9. Prime editing - Wikipedia

    en.wikipedia.org/wiki/Prime_editing

    Prime editing is a 'search-and-replace' genome editing technology in molecular biology by which the genome of living organisms may be modified. The technology directly writes new genetic information into a targeted DNA site. It uses a fusion protein, consisting of a catalytically impaired Cas9 endonuclease fused to an engineered reverse ...
