Definition
CRISPR is an acronym standing for Clustered Regularly Interspaced Short Palindromic Repeats, and refers to a genomic pattern found in bacteria and archaea of adjacent unique and repetitive alternating DNA fragments, constituting the genetic compound of an ancestral adaptive immune system used by prokaryotes to fight against bacteriophages and plasmids. A set of CRISPR-associated (Cas) proteins, most with nuclease-type activities, represent the effector compound of this system. Currently, there are at least two classes, six types and 33 subtypes of CRISPR-Cas systems. About half of the bacteria and more than 80% of archaea carry at least one CRISPR-Cas system.
History
The acronym CRISPR was invented by Francis J.M. Mojica, a microbiologist from the University of Alicante (Spain) and was first used in a scientific publication in 2002 by Ruud Jansen and collaborators in Molecular Microbiology. Mojica was also the first...
