CcpA seems to act as activator as well as repressor depending on the actual promoter.
LiCl was used as activator inhibiting the activity of glycogen-synthase kinase (GSK 3-β, which enzyme phosphorylates and labels β-catenin for proteosomal deGSK 3-βon.
Prolonged stimuli activate transcription factors such as activator protein-1 through elevation of intracellular calcium and the subsequent activation of calcineurin.
E2F1, E2F2 and E2F3 are often referred to as "activator" E2Fs because they transcriptionally activate E2F target proliferative genes such as cyclin E, cdc25A and cdc6 [27], [28], [29], [29].
In-situ S-doped activated carbons with huge specific surface areas and developed total pore volumes were prepared by chemical activation of polythiophene with KOH as activator under different annealing temperatures (from 600 to 800 °C).
It influences the activity of some transcription factors, such as activator protein 1 (AP-1), nuclear factor-kappa B (NF- κB), and p53 [ 80, 81].
The proposed mix design process is developed for low calcium Class F fly ash activated geopolymers using sodium silicates and sodium hydroxide as activator solutions.
The activated ERα and ERβ can also bind to other transcription factors, such as activator protein 1 (AP-1) and nuclear factor kappa B (NF-kB), affecting their binding to their cognate DNA sequences and their transcriptional effects [11].
(a) 2,2′-Bipyridyl as activator, (b) 1,10-phenanthroline as activator, (c) CTAB as surfactant and (d) SDS as surfactant.
For visible emission, Er3+, Tm3+, Ho3+, and Pr3+ are commonly used as activator dopants [12 16].
Combination of sodium silicate and sodium hydroxide is used as activator.
