Quercetin 3, 3′, 4′, 5, 7-O- pentasulfate (QPS): A novel activator of protein disulfide isomerase

open access: yesMedicine in Drug Discovery, 2020
Aims: Design and synthesis of a novel 3, 3′, 4′, 5, 7-O- pentasulfated Quercetin (QPS) as an activator of protein disulfide isomerase (PDI). Main Methods: Based on an in silico analysis we show that QPS binds to a and b domain of PDI (−7.4 kcal/mol ...

The synthesis of hemoglobin in a cell-free system [PDF]

open access: yes, 1958
The microsomal particles (1) have been implicated as the major sites of protein synthesis within the cells of a variety of tissues. The studies of Borsook, Zamecnik, Hultin, and others, with intact animals and various types of whole cell systems (see ...

Modest Declines in Proteome Quality Impair Hematopoietic Stem Cell Self-Renewal. [PDF]

open access: yes, 2020
Low protein synthesis is a feature of somatic stem cells that promotes regeneration in multiple tissues. Modest increases in protein synthesis impair stem cell function, but the mechanisms by which this occurs are largely unknown.

Identification of the growth arrest and DNA damage protein GADD34 in the normal human heart and demonstration of alterations in expression following myocardial ischaemia [PDF]

open access: yes, 2006
Growth arrest and DNA damage protein 34 (GADD34) is a multifunctional protein upregulated in response to cellular stress and is believed to mediate DNA repair and restore protein synthesis. In the present study we have examined GADD34 immunoreactivity in

Cell-free protein synthesis from genomically recoded bacteria enables multisite incorporation of noncanonical amino acids

open access: yesNature Communications, 2018
Cell-free protein synthesis has emerged as a powerful approach for expanding the range of genetically encoded chemistry into proteins. Unfortunately, efforts to site-specifically incorporate multiple non-canonical amino acids into proteins using crude ...

Hsp70 in mitochondrial biogenesis [PDF]

open access: yes, 1994
The family of hsp70 (70 kilodalton heat shock protein) molecular chaperones plays an essential and diverse role in cellular physiology, Hsp70 proteins appear to elicit their effects by interacting with polypeptides that present domains which exhibit non ...

Asparagine promotes cancer cell proliferation through use as an amino acid exchange factor. [PDF]

open access: yes, 2016
Cellular amino acid uptake is critical for mTOR complex 1 (mTORC1) activation and cell proliferation. However, the regulation of amino acid uptake is not well-understood.

Branched-chain amino acids and muscle protein synthesis in humans: myth or reality?

open access: yesJournal of the International Society of Sports Nutrition, 2017
The branched chain amino acids (BCAAs) are leucine, valine and isoleucine. A multi-million dollar industry of nutritional supplements has grown around the concept that dietary supplements of BCAAs alone produce an anabolic response in humans driven by a ...

Interplay of Endosomal pH and Ligand Occupancy in Integrin α5β1 Ubiquitination, Endocytic Sorting, and Cell Migration

open access: yesCell Reports, 2015
Membrane trafficking of integrins plays a pivotal role in cell proliferation and migration. How endocytosed integrins are targeted either for recycling or lysosomal delivery is not fully understood.
