Now online! Structural basis of a SWI/SNF-associated transcription pre-initiation complex

Structural basis of a SWI/SNF-associated transcription pre-initiation complex

Cryo-EM and genetic analyses reveal that the SWI/SNF chromatin remodeler is an integral component of the transcription pre-initiation complex. The structures demonstrate how SWI/SNF facilitates transcription initiation through stabilization of PIC organization and concerted remodeling of the +1 nucleosome.

Here's the official announcement of Parton's passing from her reps, along with the request that in lieu of flowers, the family asks for donations to be made to Dolly Parton’s Imagination Library at www.imaginationlibrary.com

NASHVILLE, TN (August 25, 2026) – Global icon and humanitarian, Dolly Parton, known to the world as a beloved singer, songwriter, philanthropist, actress, playwright, and author died peacefully today in Nashville, Tennessee. She was 80 years old. Dolly is preceded in death by her beloved husband of 59 years Carl Thomas Dean (1942 – 2025), her mother Avie Lee Caroline Owens (1923 – 2003), and father, Robert Lee Parton, Sr. (1921 – 2000). A rhinestone life that shone bright enough for the world to see, Dolly will forever stand as an inspiration not only through her timeless music and prolific songwriting, but also her wit, warmth, and kindness that made us all feel like family. Dolly Parton’s legacy is one of love, compassion, and resilience. With a seven-decade career, she inspired multiple generations of artists and fans with her music and an unwavering commitment to making the world a better place. Her songs will continue to resonate with people of all ages, and her philanthropic work will have a lasting impact. At Dolly’s request, a small, private service will be held for immediate family. Dolly’s fans and friends from around the world are encouraged to pay tribute to Dolly on social media by tagging @DollyParton or by leaving a message at www.dollyparton.com. In lieu of flowers the family asks for donations to be made to Dolly Parton’s Imagination Library at www.imaginationlibrary.com.

Dolly Parton, among a thousand other amazing things she did in her life, gifted over 330 million books to kids through her Imagination Library program. Her passing is a tremendous loss to the world, but you can support the program today to keep it going imaginationlibrary.com

How do nuclear compartments form inside cell nuclei? We show RNA glues certain loci together to form a nuclear compartment. This involves special GC-rich regions of highly expressed genes that also associate with nuclear speckles, but interactions between these loci are independent of speckles!

Now online! Happy to have been part of this remarkable study on TDP-43 from the Butcher Lab @uwbiochem.bsky.social www.nature.com/articles/s41...

TDP-43 controls RNA structure through high affinity lattice interactions - Nature Communications

TDP-43 is an essential RNA-binding protein. Here, the authors show how it binds single-stranded poly(UG) RNA through high affinity 1D lattice interactions. The N-terminal domain functions to accelerat...

Single-cell 3D genome imaging shows super-enhancer hubs are rare, nonspecific, and neither necessary nor sufficient for transcriptional bursting

Super-enhancers have been proposed to cluster in the nucleus when compared to other genomic elements. Le et al. found that super-enhancer clustering was rare and driven by non-specific interactions. P...
