US Patent 11970719 Class 2 CRISPR/Cas compositions and methods of use

Provided are compositions and methods that include one or more of: (1) a Class 2 CRISPR/Cas effector protein, a nucleic acid encoding the effector protein, and/or a modified host cell comprising the effector protein (and/or a nucleic acid encoding the same); (2) a CRISPR/Cas guide RNA that binds to and provides sequence specificity to the Class 2 CRISPR/Cas effector protein, a nucleic acid encoding the CRISPR/Cas guide RNA, and/or a modified host cell comprising the CRISPR/Cas guide RNA (and/or a nucleic acid encoding the same); and (3) a CRISPR/Cas transactivating noncoding RNA (trancRNA), a nucleic acid encoding the CRISPR/Cas trancRNA, and/or a modified host cell comprising the CRISPR/Cas trancRNA (and/or a nucleic acid encoding the same).
