Biologic activity in a fragment of recombinant human interferon α [PDF]

open access: yes, 1984
To attempt to locate functionally important regions of the interferon (IFN) molecule, recombinant human IFN-α2 was subjected to proteolytic digestion. The bacterial proteinase thermolysin produced two major complementary fragments, HuIFN-α2-(1-110) and ...

Use of capillary electrophoresis as a method development tool for classical gel electrophoresis [PDF]

open access: yes, 1998
Capillary electrophoresis (CE) was used to optimize the buffer pH, ionic strength and sulfated cyclodextrin concentrations for enantiomeric separation of piperoxan.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Elution of proteins from polyacrylamide eels: a simple and economic procedure

open access: yesRevista do Instituto de Medicina Tropical de São Paulo, 1989
A simplified methodology for the quantitative electroelution of proteins from polyacrylamide gels is described. After staining with Coomassie Brilliant Blue R 250, the identified bands are excised from the gel and the proteins eluted using a procedure ...

The anti‐CRISPR protein AcrIE8.1 inhibits the type I‐E CRISPR‐Cas system by directly binding to the Cascade subunit Cas11

open access: yesFEBS Letters, EarlyView.
In this study, we present the structure of AcrIE8.1, a previously uncharacterized anti‐CRISPR protein that inhibits the type I‐E CRISPR‐Cas system. Through a combination of structural and biochemical analyses, we demonstrate that AcrIE8.1 directly binds to the Cas11 subunit of the Cascade complex to inhibit the CRISPR‐Cas system.

Diversity and Dynamics of Indigenous \u3cem\u3eRhizobium japonicum\u3c/em\u3e Populations [PDF]

open access: yes, 1980
A simple method, based upon the separation of cellular proteins by sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis, has been devised for distinguishing between isolates of Rhizobium japonicum.

Purification and characterisation of a carboxylesterase from the latex ofSynadenium grantii Hook, ‘f’ [PDF]

open access: yes, 1987
The latex ofSynadenium grantii was found to contain esterolytic activity. Polyacrylamide gel electrophoretic study coupled with substrate and inhibitor specificity studies revealed the presence of multiple forms of carboxylesterases and cholinesterases ...

MicroRNA 196a contributes to the aggressiveness of esophageal adenocarcinoma through the MYC/TERT/NFκB axis

open access: yesMolecular Oncology, EarlyView.
mir‐196a promotes Esophagus Adenocarcinoma aggressiveness. On one hand, mir‐196a targets the valosin‐containing protein (VCP) mRNA, causing the accumulation of c‐MYC protein that leads to high amounts of TERT. On the other hand, mir‐196a targets the inhibitor of NFκB (NFKBIA).

Biochemical genetic polymorphism in the Indian mackerel Rastrelliger kanagurta from Mangalore region [PDF]

open access: yes, 1994
Electrophoresis is the modern and most popular technique used for studying the genetic variability within and among the populations of plants and animals. Genetically controlled tissue enzymes are the most suitable parameters for genetic variability

A nucleotide‐independent, pan‐RAS‐targeted DARPin elicits anti‐tumor activity in a multimodal manner

open access: yesMolecular Oncology, EarlyView.
We report a Designed Ankyrin Repeat Protein that binds and inhibits RAS proteins, which serve as central cell signaling hubs and are essential for the progression of many cancers. Its unique feature is that it does not discriminate between different RAS isoforms or mutations and is capable of binding to RAS in both its active (GTP‐bound) and inactive ...
