The convergence of head-on DNA unwinding forks induces helicase oligomerization and activity transition

Significance Bloom syndrome helicase (BLM) is a multifunctional helicase that primarily catalyzes the separation of two single strands of DNA. Here, using a single-molecule optical tweezers approach combined with confocal microscopy, we monitored…

The Autophagy Receptor TAX1BP1 ( T6BP ) improves antigen presentation by MHC‐II molecules

CD4 + T lymphocytes play a major role in the establishment and maintenance of immunity. They are activated by antigenic peptides derived from extracellular or newly synthesized (endogenous) proteins presented by the MHC-II molecules. The pathways…

Bloom Syndrome Helicase Compresses Single‐Stranded DNA into Phase‐Separated Condensates

Bloom syndrome protein (BLM) is a conserved RecQ family helicase involved in the maintenance of genome stability. BLM has been widely recognized as a genome "caretaker" that processes structured DNA. In contrast, our knowledge of how BLM behaves on…
