Transcription elongation by RNA polymerase II is a tightly regulated process that requires coordinated interactions between transcription elongation factors. IWS1 (Interacts with SPT6) has been implicated as a core elongation factor, but its molecular...

Poxviruses are double-stranded DNA viruses with large genomes. Among them, monkeypox virus (MPXV) has been responsible for two recent public health emergencies as declared by the World Health Organization1. The MPXV polymerase comprises three subunits—a...

Targeted protein degradation is a powerful pharmacological strategy that harnesses the ubiquitin proteasome system to eliminate disease-relevant proteins, including otherwise undruggable proteins1. Here we report an unbiased and broadly applicable...

The divisome apparatus synthesizes septal peptidoglycan (PG) during bacterial division. In Escherichia coli, the class A penicillin-binding protein (aPBP) called PBP1b has been implicated in division, but its role in the process has remained unclear. Here...

Lysine acetyltransferases (KATs) cooperate with oncogenes such as c-Myc, estrogen receptor, and lysine methyltransferase 2A (KMT2A) fusions to sustain malignant programs. Targeting of KAT proteins has shown clinical efficacy; however, achieving homolog...

The proteasome is the molecular machine responsible for most intracellular protein degradation. Proteolysis occurs within its central core particle which is regulated by different binding partners, including the regulatory particle (RP), PA28, and Blm10...

The outer membrane of Gram-negative bacteria contains a wide variety of integral β-barrel proteins. Here, we study the conserved β-barrel assembly machine which is responsible for folding and inserting these membrane β-barrels. By determining the...

The cellular nucleotide pool is a major focal point of the host immune response to viral infection. Immune effector proteins that disrupt the nucleotide pool enable animal and bacterial cells to broadly restrict diverse viruses, but reduced nucleotide...

Most viruses extensively remodel their host cells to establish productive infection. Visualization of virus-induced cellular remodeling by electron microscopy (EM) has been revolutionized in recent years by advances in cryo-focused ion beam (cryo-FIB)...

Herpesviruses are widespread double-stranded DNA viruses that establish lifelong latency and cause various diseases. Although DNA-polymerase-targeting antivirals are effective, increasing drug resistance underscores the need for alternatives. Helicase...

Mitochondrial gene expression is essential for oxidative phosphorylation. Mitochondrial-encoded mRNAs are translated by dedicated mitochondrial ribosomes (mitoribosomes), whose regulation remains elusive. In Saccharomyces cerevisiae, nuclear-encoded...

Rod-shaped bacteria rely on the Rod complex to synthesize and maintain their peptidoglycan (PG) cell wall during growth. While the enzymatic machinery at its core is well studied, the role of accessory proteins within the complex remains unclear. In this...
