This research explores the specialized architecture and defensive utility of umbrella toxins, which are large protein complexes used by Streptomyces bacteria to inhibit competitors. The study reveals that these toxins employ a two-tiered molecular bet-hedging strategy to navigate the vast structural diversity of target cell surfaces. Utilizing cryo-electron microscopy, the authors show how the tox...去小宇宙查看完整单集简介

Ablating Prdm16 in mouse adipocytes causes a loss of beige fat identity, leading to vascular remodeling, fibrosis, and hypertension. This process is driven by the derepression of QSOX1, a secreted enzyme. Deleting Qsox1 prevents these cardiovascular defects in mice.
