FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Apports et utilisation de la prospective « Protéines »
Oléagineux, Corps gras, Lipides, 2002 Les multiples facettes du « système protéines » et la nécessité de les considérer simultanément pour réfléchir à l’avenir : Quel doit être l’objet d’une prospective sur les protéines à l’Inra ? Quel est le système étudié ? Cette question est fondamentale

Genetic variation in plasma transferrins of tambaqui, Colossoma macropomum (CUVIER 1818)
, 1985 Blood specimens of tambaqui, Colossoma macropomum, an Amazonian fish of commercial importance, were examined for transferrin variants by treating blood plasma specimens with rivanol before electrophoretic analyses in starch gel media.
