domain fusion
Taxonomy: Technique Branch / Method. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Domain fusion is a protein engineering method in which protein domains are fused or split to improve existing protein functions or create novel functions. In the supplied evidence, it is described as a general strategy for expanding CRISPR-Cas9 applications.
Usefulness & Problems
Why this is useful
This method is useful because it provides a general route to alter or extend protein function, including in CRISPR-Cas9 systems. The cited context links such engineering strategies to applications spanning gene therapy, gene regulation, epigenome modification, and chromosome imaging.
Source:
CRISPR-Cas9 has been used in a wide variety of applications ranging from basic science to the clinic, such as gene therapy, gene regulation, modifying epigenomes, and imaging chromosomes.
Problem solved
In the supplied evidence, domain fusion is relevant to addressing limitations that restrict broader CRISPR-Cas9 use. These limitations include aberrant off-target activity, strict protospacer-adjacent motif dependence, and the large size of Cas9 that complicates delivery.
