New research chalks this resilience up to a protein that shields healthy cells from stress — a finding that tags the protein as a potential target for future antitumor drugs.
It has long been known that cells tag proteins for degradation by labelling them with ubiquitin, a signal described as «the molecular kiss of death.»
Without the acetyl groups tagging proteins, the plant didn't recognize them as foreign and thus didn't mount a cell - killing immune response.
In this study, the researchers found that macrophages from mice lacking Smurf1 were unable to attach the death - tagging protein ubiquitin to intracellular bacteria, resulting in a failure of the autophagy pathway and runaway growth of the bacteria inside the cells.
To test this hypothesis the researchers tagged this protein in tissue with varying forms of fibrosis, and found that these cells proliferated by almost 20-fold under chronic injury and turned into myofibroblasts.

Jun. 27, 2012 — An interdisciplinary team of scientists have successfully tagged a protein that regulates the neurotransmitter serotonin with tiny fluorescent beads, allowing them to track the movements of individual molecules for the first time.
Additionally, thanks to the modular arrangement of vectors included in tagging systems like SapTrap, scientists will be able to generate genome - wide libraries containing fluorescently - tagged proteins at endogenous loci, shedding light on previously unknown protein functions.
The group also found that mNeonGreen works well for GFP's typical applications, from tagging proteins to labelling subcellular compartments, and that the protein is as stable against photodegradation as GFP.
Overexpression of fluorescently tagged proteins can lead to improper protein localization, protein aggregation, or disruption of normal protein function, and ultimately misinterpretation of the protein's cellular role.
Rice University scientists have discovered a method to tag proteins with a controllable enzyme switch.
Ubiquitin ligases are involved in tagging proteins for degradation, they're very important in degradative mechanisms involving the proteasome.
The researchers used an azidonorleucine (Anl) amino acid to tag proteins in Escherichia coli bacteria cells.
Ding's team took cells called fibroblasts from the connective tissues of mouse fetuses and bathed them in a cocktail of the four polyarginine - tagged proteins for 12 hours, then they removed the reprogramming proteins for 36 hours, and repeated this cycle four times over.
Further experiments revealed that Cue1p binds to the tagging protein Ubc7p.
An integrative approach to data generation includes strict validation criteria using gene silencing, paired antibodies, and fluorescently tagged proteins.
The researchers were able to visualize the process because the protein aggregates were labeled with different fluorescently tagged proteins that bind to aggregates.
These tags often change the location or function of the tagged protein.
They found that the tagged protein, as expected, interacts with many other proteins, for example previously identified helper proteins, so - called transcription factors.
We have followed up on our RNAi screens by developing methods to tag proteins in large pieces of genomic DNA, using recombineering.
To detect protein - protein interactions (or conformational changes) between fluorescently tagged proteins, FRET can be used, since it provides a higher spatial resolution.
To purify many proteins in parallel for comparative screening, a custom - built protein purification system was employed, that enables the simultaneous purification of up to 96 His - tagged proteins, even from large (> 50 mL) tissue culture volumes [33].
N - terminal GST - and His6 - tagged proteins are purified and printed on glass slides in duplicate, along with control proteins (GST, BSA, Histones, IgG, etc..)
