Microtubules scaffold cells, supporting signaling and cargo transport. They assemble from GTP-tubulin, which hydrolyzes to GDP-tubulin during polymerization. GTP-microtubule lattices are stable; GDP lattices depolymerize rapidly. In vitro, ...

In mammals, glucose transporters (GLUTs) mediate organism-wide sugar distribution, yet the molecular basis of substrate specificity remains unclear. The bacterial xylose transporter XylE serves as a model for GLUTs. However, although xylose...

Mitochondria contain their own genome, mitochondrial DNA (mtDNA), which is under strict control by the cell nucleus. mtDNA occurs in many copies per cell and mutations often only affect a proportion of them, giving rise to heteroplasmy. mtD...
Resolution of R-loops and transcription-replication conflicts by SETX-BRCA1-BARD1 complex [0.03%]
SETX-BRCA1-BARD1复合体解决R环和转录-复制冲突的作用

Senataxin (SETX), an RNA-DNA helicase, accumulates at transcription pause sites through the tumor suppressor BRCA1. Here, we provide mechanistic insight into how SETX-BRCA1 resolves transcription-associated R-loops to prevent deleterious ou...
Condensate protein aggregation in ALS/FTD is regulated by GGGGCC-repeat RNA scaffolds [0.03%]

IscB, a compact Cas9 ancestor from the obligate mobile element guided activity system, has attracted growing interest as a programmable genome editor because of its small size and therapeutic delivery potential. Despite its promise, structu...
