Genome editing using CRISPR, CAST, and Fanzor systems

초록

Genetic engineering technologies are essential not only for basic science but also for generating animal models for therapeutic applications. The clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein (Cas) system, derived from adapted prokaryotic immune responses, has led to unprecedented advancements in the field of genome editing because of its ability to precisely target and edit genes in a guide RNA-dependent manner. The discovery of various types of CRISPR-Cas systems, such as CRISPR-associated transposons (CASTs), has resulted in the development of novel genome editing tools. Recently, research has expanded to systems associated with obligate mobile element guided activity (OMEGA) RNAs, including ancestral CRISPR-Cas and eukaryotic Fanzor systems, which are expected to complement the conventional CRISPR-Cas systems. In this review, we briefly introduce the features of various CRISPR-Cas systems and their application in diverse animal models. (c) 2024 The Author(s).
