Vieillissement moléculaire des protéines [PDF]

open access: yes, 2017
Le vieillissement moléculaire des protéines correspond aux modifications non enzymatiques que subissent celles-ci au cours de leur vie biologique et qui conduisent à l’altération de leurs propriétés structurales et fonctionnelles.

Cryptic genetic variation shapes the fate of gene duplicates in a protein interaction network

open access: yesNature Communications
Paralogous genes are often functionally redundant for long periods of time. While their functions are preserved, paralogs accumulate cryptic changes in sequence and expression, which could modulate the impact of future mutations through epistasis.

Remplacement partiel des protéines du lait par celles du blé ou du maïs dans les aliments d’allaitement : influence sur l’utilisation digestive chez le veau de boucherie

open access: yesINRAE Productions Animales, 1990
Le but de cet essai était d’étudier l’influence du remplacement d’une partie des protéines du lait par celles du blé ou du maïs, sur la digestibilité de l’aliment et la rétention azotée, chez le veau de boucherie.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Understanding the Significance and Implications of Antibody Numbering and Antigen-Binding Surface/Residue Definition

open access: yesFrontiers in Immunology, 2018
Monoclonal antibodies are playing an increasing role in both human and animal health. Different strategies of protein and chemical engineering, including humanization techniques of non-human antibodies were applied successfully to optimize clinical ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS 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 ...

Oligomérisation des protéines humaines et virales à sept domaines transmembranaires [PDF]

open access: yes, 2012
Les récepteurs couplés aux protéines G (RCPG), aussi appelés protéines à sept domaines transmembranaires (7TM), représentent la plus grande famille de protéines. Elle comprend, chez l’homme, environ 900 membres.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS 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.

Amélioration des activités insecticides des protéines Vip3 de Bacillus thuringiensis

open access: yesRevue Marocaine des Sciences Agronomiques et Vétérinaires, 2016
Les protéines Vip3 sont des biopesticides de deuxième génération synthétisées et sécrétées par Bacillus thuringiensis au cours de la phase végétative. Ces protéines, découvertes au milieu des années 1990, présentent un grand intérêt pour lutter contre ...
