Abstract

The development of mutant microorganisms lacking J domain proteins (JDPs; formerly called Hsp40s) has enabled the development of complementation assays for testing the co-chaperone function of JDPs. In these assays, an exogenously expressed novel JDP is tested for its ability to functionally substitute for a non-expressed or nonfunctional endogenous JDP(s) by reversing a stress phenotype. For example, the in vivo functionality of prokaryotic JDPs can be tested on the basis of their ability to reverse the thermosensitivity of a dnaJ cbpA mutant strain of the bacterium Escherichia coli (OD259). Similarly, the in vivo functionality of eukaryotic JDPs can be assessed in a thermosensitive ydj1 mutant strain of the yeast Saccharomyces cerevisiae (JJ160). Here we outline the use of these thermosensitive microorganisms in complementation assays to functionally characterize a JDP from the bacterium, Agrobacterium tumefaciens (AgtDnaJ), and a JDP from the trypanosomal parasite, Trypanosoma cruzi (TcJ2).

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. 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 06 August 2023.
All research outputs
#20,587,875
of 25,295,968 outputs
Outputs from Methods in molecular biology
#8,925
of 14,174 outputs
Outputs of similar age
#350,048
of 476,778 outputs
Outputs of similar age from Methods in molecular biology
#511
of 722 outputs
Altmetric has tracked 25,295,968 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 14,174 research outputs from this source. They receive a mean Attention Score of 3.5. This one is in the 22nd percentile – i.e., 22% 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 476,778 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 15th percentile – i.e., 15% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 722 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
