Cas9
Cas9
Cas9 (pronounced "C-A-S-nine") is a nuclease protein used in the CRISPR gene editing system.
Etymology
The term "Cas9" is an abbreviation for "CRISPR associated protein 9". The name is derived from the system's original discovery in bacterial immune systems, where it was found to be associated with Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR).
Function
In the CRISPR system, Cas9 plays a crucial role in the process of DNA editing. It acts as a pair of "molecular scissors," cutting the DNA at a specific location so that genes can be added or removed. The location of the cut is determined by a guide RNA molecule, which binds to Cas9 and directs it to the correct location on the DNA strand.
