Welcome to CRISPRs web server. This site acts as a gateway to publicly accessible CRISPRs database and software. It enables the easy detection of CRISPRs in locally-produced data and consultation of CRISPRs present in the database. It also gives information on the presence of CRISPR-associated (cas) genes when they have been annotated as such.
This web site is the product of an original work by Ibtissem Grissa (PhD thesis Paris University), improved by Christine Drevet, and presently developed by David Couvin.
