SUMMARY:RNA Innovation Seminar: Zhonggang Hou & Jun Hee Lee
DESCRIPTION:“Harnessing diverse compact CRISPR-Cas3 for long-range genome engineering”\nZhonggang Hou\, Ph.D.\nResearch Investigator\nBiological Chemistry \nABSTRACT: Leading CRISPR-Cas technologies employ Cas9 and Cas12 enzymes that generate RNA-guided dsDNA breaks. Yet\, the most abundant microbial adaptive immune systems\, Type I CRISPR\, is under-exploited for eukaryotic application. I will discuss our effort on adopting the first minimal CRISPR-Cas3 from Neisseria Type I-C system\, to create targeted large chromosomal deletions in human cells. RNP delivery of the processive Cas3 nuclease and target recognition complex Cascade\, gave up to 90% editing efficiency. Unexpectedly\, Type I-C Cascade assembly in bacteria requires a previous unknown internal translation product Cas11 from within the cas8 gene. Our data show that expression of a separately encoded Cas11 is the key to enable plasmid- and mRNA- based editing in human cells. We demonstrate that “supplying cas11” is a universal strategy to harness divergent and streamlined Type I-C\, I-D and I-B editors with distinct PAM preferences and guide orthogonality. Our findings expand the CRISPR toolbox for long-range genome engineering. \nKEYWORDS: CRISPR; genome editing; Cascade; Cas3; Cas11; DNA targeting; crRNA; large deletion; Neisseria; genome engineering \n  \n  \n“Microscopic Examination of Spatial Transcriptome through Seq-Scope”\nJun Hee Lee\, Ph.D.\nAssociate Professor\nMolecular & Integrative Physiology \nKEYWORDS: Spatial Transcriptomics\, Seq-Scope \n  \nRegistration: https://umich.zoom.us/webinar/register/WN_qBK6mw7vQa6jOkZuS81_VQ \nFLYER IN PDF
