First-ever preprint from our lab, describing evidence that the RPA-Trt1-Tpz1 complex contributes to telomerase activation in fission yeast.

This story began when Yong-jie Xu from Wright State University sent us a collection of 25 Replication Protein A subunit Ssb1 (RPA1) mutants in 2021.

Our paper in Science is out! @souravagrawal.bsky.social, @rlynn.bsky.social, @susvirkar.bsky.social, and the rest of the team show human RPA is a telomerase processivity factor essential for telomere maintenance. This reshapes our thinking about telomerase regulation. www.science.org/doi/10.1126/...
Human RPA is an essential telomerase processivity factor for maintaining telomeres
Telomerase counteracts telomere shortening by repeatedly adding DNA repeats to chromosome ends. We identified the replication protein A (RPA) heterotrimer as a telomerase processivity factor critical ...

Exhausted with trying multiple ways to combat the air-water interface (AWI) problem during sample grid plunge freezing? We may have an easy solution for you!
Read our latest preprint on how we use LEA proteins as AWI sample protectants for challenging samples: www.biorxiv.org/content/10.1...
Small LEA proteins as an effective air-water interface protectant for fragile samples during cryo-EM grid plunge freezing
Sample loss due to air-water interface (AWI) interactions is a significant challenge during cryo-electron microscopy (cryo-EM) sample grid plunge freezing. We report that small Late Embryogenesis Abundant (LEA) proteins, which naturally bind to AWI, can protect samples from AWI damage during plunge freezing. This protection is demonstrated with two LEA proteins from nematodes and tardigrades, which rescued the cryo-EM structural determination outcome of two fragile multisubunit protein complexes. ### Competing Interest Statement The authors have declared no competing interest.
