Chemical and biological labeling is fundamental for the elucidation of the function of proteins within biochemical cellular networks. In particular, fluorescent probes allow detection of molecular interactions, mobility and conformational changes of proteins in live cells with high temporal and spatial resolution. We present a generic method to label proteins in vivo selectively, rapidly (seconds) and reversibly, with small molecular probes that can have a wide variety of properties. These probes comprise a chromophore and a metal-ion-chelating nitrilotriacetate (NTA) moiety, which binds reversibly and specifically to engineered oligohistidine sequences in proteins of interest. We demonstrate the feasibility of the approach by binding NTA-chromophore conjugates to a representative ligand-gated ion channel and G protein-coupled receptor, each containing a polyhistidine sequence. We investigated the ionotropic 5HT(3) serotonin receptor by fluorescence measurements to characterize in vivo the probe-receptor interactions, yielding information on structure and plasma membrane distribution of the receptor.

Attention Score in Context

This research output has an Altmetric Attention Score of 7. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 February 2020.
All research outputs
of 15,625,875 outputs
Outputs from Nature Biotechnology
of 7,078 outputs
Outputs of similar age
of 14,658,373 outputs
Outputs of similar age from Nature Biotechnology
of 7,042 outputs
Altmetric has tracked 15,625,875 research outputs across all sources so far. Compared to these this one has done well and is in the 81st percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 7,078 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 31.6. This one is in the 49th percentile – i.e., 49% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 14,658,373 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 81% of its contemporaries.
We're also able to compare this research output to 7,042 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 50% of its contemporaries.
