FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

, 2008 BACKGROUND: Chondroitin sulfate (CS) is a glycosaminoglycan released by activated platelets. OBJECTIVE: Here we test the hypothesis that CS released by activated platelets can trigger complement activation in the fluid phase.

CTPS2 regulates CTP synthetase activity by interacting with CTPS1
Life Science AllianceThe human CTP synthetases 1 and 2 associate together and co-localize in large filament–cytoophidium structures. CTPS1 and CTPS2 association results in enzymatic modulation independently of cytoophidia revealing a new regulation mechanism of CTP ...

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

IKKα regulation of canonical NF-κB activation downstream of Nod1-mediated peptidoglycan recognition : "and" Endocytosis-independent function of clathrin heavy chain in the control of basal NF-κB activation [PDF]
, 2010 NF-κB is a transcription factor involved in the regulation of inflammation and innate immunity. The IκB kinase (IKK) complex contains two catalytic subunits, IKKα and IKKβ, and plays an essential role in the activation of NF-κB through the ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Transcriptional reprogramming via signaling domains of CD2, CD28, and 4-1BB
iScienceSummary: Costimulatory signals provided to T cells during antigen encounter have a decisive role in the outcome of immune responses. Here, we used chimeric receptors harboring the extracellular domain of mouse inducible T cell costimulator (mICOS) to ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified
