Genetic variation in plasma transferrins of tambaqui, Colossoma macropomum (CUVIER 1818)

open access: yes, 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.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

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 ...

Les protéines de choc thermique (heat shock proteins). I : Classification, structure, fonctions et implications dans les processus pathologiques [PDF]

open access: yes, 2002
All living systems have evolved mechanisms to maintain homeostasis in the face of rapid environmental changes. When exposed to elevated temperatures, most of the cells activate the synthesis of a specific group of proteins called Heat Shock Proteins ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Lipophilisation des protéines biocatalysées par des lipases : cas des isolats de protéines de soja [PDF]

open access: yes, 1997
La lipophilisation par biocatalyse a été effectuée sur des isolats de protéines de soja, riches en lysine. Les réactions ont été conduites à 60 degrés C avec et sans solvant en mettant en oeuvre une lipase fixée (lipozyme) ou libre (lipase S de Rhizopus ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

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 ...
