The Expanding Influence of CRISPR in Biotechnology
CRISPR systems play a critical role in the development of various innovative biomolecular techniques, especially those involving CRISPR/Cas-mediated genome editing. Discovering new CRISPR systems can greatly enhance these biotechnological applications, potentially leading to more effective and safer genomic therapies. The expansion of the CRISPR toolbox typically involves computational analyses of protein sequence databases.
FLSHclust: A Breakthrough in Protein Data Analysis
Current algorithms struggle to manage the surging size of datasets containing billions of proteins. To address this issue, Han Altae-Tran and his team developed FLSHclust (fast locality-sensitive hashing-based clustering), an innovative algorithm that clusters proteins based on their sequence similarity. This tool enables the rapid and efficient analysis of large protein sequence databases, a task that existing methods have found challenging.
Groundbreaking Research and Findings
Altae-Tran and his team applied the FLSHclust algorithm to an 8.8 terrabase pair metagenomic database, which included 8 billion proteins and 10.2 million CRISPR arrays. This analysis resulted in the discovery of 188 previously unknown CRISPR-associated genes. A notable finding was the identification and detailed description of a new class of CRISPR system, containing Cas-14 and type VII, which targets RNA.
The Rarity and Potential of Newly Identified CRISPR Systems
The research revealed that the newly identified systems are rare, with many represented by a single cluster among the approximately 130,000 CRISPR-linked clusters identified through FLSHclust.
The authors state, “The discovery of previously unknown cas genes and CRISPR systems substantially broadens the known scope of CRISPR diversity. This emphasizes the functional versatility of CRISPR, wherein often previously undiscovered proteins and domains are recruited. These can replace existing components or add new functions to the Cas protein scaffold.”
They further note, “The findings highlight the unprecedented organizational and functional flexibility and modularity of CRISPR systems. However, it also shows that most variants are rare and predominantly found in relatively unusual bacteria and archaea.”

Han Altae-Tran’s work sounds groundbreaking, would love to see more about their team’s research in future articles
read about CRISPR before but this article really puts into perspective how far we’ve come, still a bit over my head tho
this is huge, finding 188 new gene modules? that’s insane, kudos to the researchers
interesting stuff but felt a bit too technical for me, could use simpler explanations maybe?
wow, this FLSHclust thing sounds amazing, didn’t know we had this kinda tech for CRISPR, great for science!
great article, but there’s a typo in the 3rd paragraph, should check that out
