For screening using two-dimensional (2D) NMR, we identified the indicative signals in the KRS anticodon-binding domain and selected inhibitors that bind to KRS and compete with LR at the KRS-LR binding interface.
The peak at residue start positions 21-25 indicativeive of signal peptide cleavage, another well-known post-translational modification.
On protein protein association these fragments (typically of yellow fluorescent protein, YFP) are brought together to allow refolding, chromophore maturation, and thus an indicative fluorescent signal.
Increased reactive oxygen species (ROS) production or changes in intracellular glutathione levels are often involved with pathological changes, both of which are indicative of signal cascade, or gene expression dysregulation (Waris and Ahsan, 2006).
Perhaps this is indicative of signalling between these two subtypes.
EGF receptor and ErbB-2 are present in stroma and epithelium, and are tyrosine-phosphorylated, which is indicative of signaling activity [ 37**, 38**].
In addition to the expected nEPSCs recorded at −70 mV, we also observed barrages of outward inhibitory postsynaptic currents (IPSCs) at 0 mV, indicative of signaling through GABA receptors (n = 28 of 58 cells, Figure 1E, center).
The results are surprising but are consistent with the observation of Pratilas et al. [ 44], who found that ERK phosphorylation was not indicative of signalling through the MEK pathway, as ERK phosphorylation is also regulated by negative feedback loops.
A comparison of vertical profiles of the organic and inorganic parts of the biofilm indicated that the reflection signal (indicative for inorganic material) was consistently higher than the organic matter throughout the depth of biofilm.
However, our experiments show that DTKR expression levels influence DILP levels in the principal cells, especially at starvation, and we will next show that the DTK signaling influences physiological phenomena indicative of DILP signaling.
