CRISPRlnc: a manually curated database of validated CRISPR/Cas9 sgRNAs for lncRNAs
The first step of CRISPR/Cas9 gene editing is to design a single guide RNAs (sgRNA) to target your gene of interest. However, because sgRNAs vary widely in their activity and models, designing a sgRNA is not easy with an unwarrantable effectiveness. Thus, it is worthy of collecting validated sgRNAs, to assist in efficiently choosing sgRNA with an expected activity.
CRISPRlnc is a manually curated database of validated CRISPR/Cas9 sgRNAs for lncRNAs from all species. After manually reviewing more than 200 published literature, CRISPRlnc collected hundreds of lncRNAs and thousands of validated sgRNAs. We handled the ID, position in the genome, sequence and functional description of these lncRNAs, as well as the sequence, PAM motif, CRISPR type and validity of these sgRNAs.
Until now, tools with various characteristics for ab initio designing sgRNA are crowded, whereas systematic collection of validated sgRNA is rare. As the first database against the validated sgRNAs of lncRNAs, CRISPRlnc will provide a new and powerful approach for genome editing of lncRNAs. We believed that our CRISPRlnc database will thrive in the fields related to lncRNA and CRISPR/Cas9 studies, and will be popular among people in these fields.
31 May 2020, across 10 species, lncRNAs and validated sgRNAs in CRISPRlnc have increased to 335 and 2184.
12 February 2019, lncRNAs and validated sgRNAs in CRISPRlnc have increased to 311 and 2123.
16 September 2018, lncRNAs and validated sgRNAs in CRISPRlnc have increased to 305 and 2102. Some minor changes were made to improve the usability of the website.
