The CasRfg.3 (also referred to as Ca2) protein of the present disclosure has a relatively shorter amino acid sequence compared to the commonly used SpCas9 protein, allowing it to be easily packaged into small-capacity gene therapy vectors. The CasRfg.3 corresponds to a unique PAM sequence. Additionally, the CasRfg.3 exhibits excellent specificity in targeting and editing nucleic acid sequences, shows good adaptation to temperature variations, and has a wide temperature tolerance range, functioning effectively under high-temperature conditions, such as being capable of cleaving or modifying target nucleic acids at temperatures ranging from 25° C. to 55° C. The novel Cas effector protein of the present disclosure has significant application value in fields like gene therapy.
