- * To address and mitigate off-target effects in CRISPRi applications.
- * To provide a user-friendly platform for prokaryotic CRISPRi library design.
Main Methods:
- * Development of a web-based tool (GLiDe) for sgRNA library design.
- * Incorporation of a quality control framework based on experimental data to identify off-target hits.
- * Utilization of an extensive built-in database of 1,397 prokaryotic species.
- * Option to design sgRNAs for novel organisms using uploaded data.
Main Results:

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.
