mCherry lysate looking good! Ice bucket is blown away @DNAcurtain

@jpkbravo #3 does not disappoint! Love that you captured the elusive NTS. Congrats all!

Happy Transposon Day 2022! Today is the 120th birthday of Barbara McClintock, founder of the #transposon field and Nobel laureate. Please celebrate with us by using the hashtag #TransposonDay2022. How has Barbara McClintock or her work influenced you? https://t.co/rRm70T0MUf

Transposons take over #CRISPR2022! @JoePetersLab @MariuszCzC @PhoebeARice

[Mariusz Czarnocki-Cieciura @MariuszCzC]

Very happy to announce our TnsB paper is out! It includes 2.7 Å cryo-EM structure of transposase bound to transposon end. Wonderful collaboration with @JoePetersLab.

Happy #TransposonDay2021 from the Peters Lab at Cornell University, Barbara McClintock's training ground!

[Mike Petassi @MikePetassi]

Congrats to @kellogg_liz and co for the first lab pre-print and very happy to be on board! More Tn7-like transposon structure and mechanism to see, this time of the #CRISPR-Cas wielding RNA-guided variety.

[Liz Kellogg ❄️🔬 @kellogg_liz]

The @kellogg_liz lab has posted its first pre-print! Here we continue our mechanistic studies of 'jumping genes' or transposases, in close collaboration with @JoePetersLab on CRISPR-associated transposases ( Type V-K CAST elements).

Excited to be a part of this awesome work from @shen_yao10 and @alba_guarne lab! Finally get to see this piece of the mighty Tn7 transposon!

[Alba Guarne @alba_guarne]

Incredibly proud of this structure and @shen_yao10 work. I could not have anticipated how much it would explain @j_ortega_McGill @JoePetersLab @McGillMed

Structural basis for DNA targeting by the Tn7 transposon https://t.co/Eu2Ofz8cgT

[Mike Petassi @MikePetassi]

Expanding our understanding of dual-pathway transposition (1 - plasmids; 2 - chromosomal attachment sites) with Tn7-like elements one family at a time. New preprint from bioinformatics wizard @PopoMicro on Tn7-CRISPR-Cas12k

[Joseph E. Peters @JoePetersLab]

Tn7-CRISPR-Cas12K transposons categorize guide RNAs for different types of integration targets. Previously shown for type I-F3 systems. Grad student @PopoMicro shows an analogous process evolved with Cas12K systems. 1/6 https://t.co/vYnoyqI6ES
