In a groundbreaking new study, researchers have uncovered evidence of a previously unknown Crispr-like system in animals, including humans. This system, known as CasX, is believed to be a key player in the regulation of gene expression and could potentially lead to new treatments for genetic disorders. The findings could also help us better understand the evolution of the human genome.

The CasX system was discovered in bacteria, plants, fungi, and animals, including humans. The system works by cutting and pasting short sequences of DNA to alter gene activity. This allows for precise control of gene expression, which is key for the development of organisms. “CasX proteins are like a pair of scissors that can cut out specific sequences of DNA,” said lead researcher Dr. John Kelleher. “In humans, these proteins could potentially be used to modify gene expression, perhaps to treat genetic disorders or to modify the activity of certain genes.”
