The complex best resembles the type III-A CRISPR Csm effector complex, consisting of a Cas7-like (Csf2) filament intertwined with a small subunit (Cas11) filament, but the complex lacks subunits for RNA processing and target DNA cleavage. Surprisingly, instead of assembling around a CRISPR-derived RNA (crRNA), the complex assembles upon heterogeneous RNA of a regular length arranged in a pseudo-A-form configuration. These findings provide a high-resolution glimpse into the assembly and function of enigmatic type IV CRISPR systems, expanding our understanding of class I CRISPR-Cas system architecture, and suggesting a function for type IV-B RNPs that may be distinct from other class 1 CRISPR-associated systems."}],"intvolume":" 24","day":"19","date_published":"2021-03-19T00:00:00Z","publication_identifier":{"issn":["2589-0042"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"full_name":"Zhou, Yi","first_name":"Yi","last_name":"Zhou"},{"first_name":"Jack Peter Kelly","last_name":"Bravo","orcid":"0000-0003-0456-0753","full_name":"Bravo, Jack Peter Kelly","id":"96aecfa5-8931-11ee-af30-aa6a5d6eee0e"},{"full_name":"Taylor, Hannah N.","last_name":"Taylor","first_name":"Hannah N."},{"last_name":"Steens","first_name":"Jurre A.","full_name":"Steens, Jurre A."},{"last_name":"Jackson","first_name":"Ryan N.","full_name":"Jackson, Ryan N."},{"full_name":"Staals, Raymond H.J.","first_name":"Raymond H.J.","last_name":"Staals"},{"first_name":"David W.","last_name":"Taylor","full_name":"Taylor, David W."}],"article_processing_charge":"Yes (in subscription journal)","article_number":"102201","date_created":"2024-03-20T10:43:00Z","doi":"10.1016/j.isci.2021.102201","issue":"3","citation":{"apa":"Zhou, Y., Bravo, J.
