Differential activation of cGAS in naked mole rats! An exciting addition to our understanding of species-specific mutations tailoring the cGAS-STING pathway in individual organisms

A cGAS-mediated mechanism in naked mole-rats potentiates DNA repair and delays aging

Efficient DNA repair might make possible the longevity of naked mole-rats. However, whether they have distinctive mechanisms to optimize functions of DNA repair suppressors is unclear. We find that na...

"Jane Goodall showed us what a life in science could look like: rigorous discovery paired with fierce advocacy for what you study. She gave the world six decades of groundbreaking research on chimpanzees and their habitats, then turned that knowledge into a global movement for conservation." (1/2)

Bacteria use a decoy defence molecule to set a trap for viruses

Some bacterial-infecting viruses use ‘sponges’ to mop up defence molecules, but bacteria can fight back by responding when a sponge captures decoy molecules.

Are viruses capable of regulating protein synthesis in the nuanced way of cellular organisms? Kinda! I’m excited to share some of my postdoc work that leveraged giant DNA viruses to address this question.

Giant DNA viruses encode a hallmark translation initiation complex of eukaryotic life

In contrast to living organisms, viruses were long thought to lack protein synthesis machinery and instead depend on host factors to translate viral transcripts. Here, we discover that giant DNA virus...

Our story describing the Panoptes bacterial immune defense system is now finally peer-reviewed and published today! www.nature.com/articles/s41...

The Panoptes system uses decoy cyclic nucleotides to defend against phage - Nature

The Panoptes antiphage system defends bacteria by detecting phage-encoded counter-defences that sequester cyclic nucleotide signals, triggering membrane disruption and highlighting a broader strategy of sensing immune evasion through second-messenger surveillance.

In phage defense, an N-terminal glycine residue in the substrate protein takes the place of ammonia in canonical Q biosynthetic chemistry to create a protein-nucleobase conjugation modification named N-terminal deazaguanylation or NDG

Kranzusch Lab @kranzuschlab.bsky.social · 16d

Why defense islands would encode nucleobase biosynthetic machinery was a mystery. We searched in vain for modified nucleotides as signals in CBASS defense… until Doug surprisingly discovered a Q-like base directly conjugated to the N-terminus of a substrate protein!

In addition to ACGU, "Q" is a modified nucleobase required for tRNA maturation in bacteria, plants, and animals. Since 2020, type IV CBASS phage defense islands were known to encode proteins with homology to the enzymes QueC (Q modification) and TGT (Q installation)
