We wanted to develop an optogenetic binder that did not depend on additional genetic manipulation of the target protein. (scienceblog.com)

In the last 70 years tremendous progress has been made in their isolation, production, characterization, and finally engineering. (kdnuggets.com)
In today's presentation I will describe a new strain that we have engineered to aid the isolation of pure his-tag proteins. (neb.com)

This allows rapid access to biological data, and on-demand protein sequence prototyping. (sbir.gov)
The use of genetic engineering and modern techniques such as transcriptomics, proteomics and sequence analysis are included in the course. (lu.se)

To delineate the precise mechanism by which indisulam mediates the DCAF15-RBM39 interaction, we solved the DCAF15-DDB1-DDA1-indisulam-RBM39(RRM2) complex structure to a resolution of 2.3 Å. (nature.com)

Nanowerk News ) How a transport protein obtains its driving force from the energy storage molecule ATP, has been tracked dynamically by RUB researchers. (nanowerk.com)
Using this method, researchers can track minute changes in the protein in the range of nanoseconds. (nanowerk.com)
Researchers have created engineered proteins that lowered body weight, bloodstream insulin, and cholesterol levels in obese mice, rats, and primates. (latimes.com)
In mice who got a bioengineered version of the GDF15 protein, the researchers observed even more remarkable changes. (latimes.com)
The results suggest that the GDF15 engineered by researchers had the power to turn off the kind of reward-driven eating (think doughnuts, milkshakes or bacon cheeseburgers) that drives many of us to become obese, or to regain lost weight. (latimes.com)
The Amgen researchers accomplished this by fusing the protein with other agents that would not break down so quickly. (latimes.com)

We describe structure-guided engineering of a CRISPR-Cas9 complex to mediate efficient transcriptional activation at endogenous genomic loci. (cdc.gov)

In this way they tracked, how ATP bound to the transport protein, how one of its three phosphate groups split off and was released into the environment without first latching back on to the protein. (nanowerk.com)
We could directly image how laminin is extending from the NWs, maximizing the number of proteins bound to the NWs. (lu.se)

NEB also offers solutions for expressing these types of proteins, either in vitro or in vivo. (neb.com)
