The extracellular signal-regulated kinase ERK2, a member of the protein kinase superfamily, phosphorylates a variety of cellular proteins in response to extracellular signals. ERK2 expressed in Escherichia coli as a fusion protein with the sequence Ala-His6 at the N terminus has low basal activity and very low levels of phosphate incorporation, but can be fully activated. The Ala-His6 ERK2 as expressed in the unphosphorylated form has been crystallized in space group P2(1). The cell constants are a = 49.32 A, b = 71.42 A, c = 61.25 A, and beta = 109.75 degrees, and the crystals diffract to better than 1.8 A resolution.
This research output has an Altmetric Attention Score of 3. 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 25 May 2010.
All research outputs
#9,515,738
of 27,781,301 outputs
Outputs from Journal of Molecular Biology
#5,107
of 12,287 outputs
Outputs of similar age
#7,139
of 22,435 outputs
Outputs of similar age from Journal of Molecular Biology
#15
of 44 outputs
Altmetric has tracked 27,781,301 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 12,287 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.7. This one is in the 16th percentile – i.e., 16% 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 22,435 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 8th percentile – i.e., 8% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 44 others from the same source and published within six weeks on either side of this one. This one is in the 4th percentile – i.e., 4% of its contemporaries scored the same or lower than it.
