2024年12月16日,生命科学学院刘亮教授团队在《Nucleic Acids Research》期刊上在线发表了题为“DNA target binding-induced pre-crRNA processing in type II and V CRISPR-Cas systems”的研究论文,首次揭示了靶标核酸的结合能够激活CRISPR-Cas系统效应蛋白对pre-crRNA的反式切割活性 ...
CRISPR-Cas9 genome editing exploits the CRISPR-Cas system to modify a genome in a targeted manner. Guided by RNA, the Cas9 endonuclease breaks DNA at a target sequence. Imprecise repair of the ...
signaling the system to initiate gene silencing. "The 'R' in R-loop stands for RNA. All DNA-binding CRISPR-Cas systems use this structure to probe the DNA sequence and identify the correct target ...
Type V CRISPR-Cas Cpf1 endonuclease employs a unique mechanism for crRNA-mediated target recognition ... We have investigated the binding of anti-CRISPR proteins to the crRNA-bound type I-F Csy ...
Yet others, called base editors, change one letter of the DNA code to another. So why do we call it CRISPR? Cas proteins are used by bacteria to destroy viral DNA. They add bits of viral DNA to ...
Researchers have been working to find CRISPR/Cas nucleases with greater specificity ... team used a GFP activation expression reporting system to screen 13 Cas12b nucleases. Interestingly, one ...
