In the case of genes encoding proteins which act as regulators, this includes establishing regulation of appropriate targets.
miRNAs are known to act as regulators in gastric cancer cell growth and to regulate gastric cancer metastasis.
In rhizobia, fur gene products do not regulate Fe-uptake systems; instead they act as regulators of Mn transporters and the genes have been renamed as mur[ 121].
Since the original observation more than a decade ago that dietary fats act as regulators of gene expression, many transcription factors and prospective targets for fatty acid regulation have been identified.

While many analysts acknowledge the very real risks of sustainable development issues such as climate change to future asset values (e.g. coal), they are not prepared to act as regulators.
Galectins are multifunctional proteins that act as regulators of various biological processes via protein-glycan interactions.
MicroRNAs (miRNAs), which are small single-stranded non-coding RNAs highly conserved across species, act as regulators of transcription efficiency by degrading and thus counteracting mRNA [14].
For instance, MyoD and myf5 are essential regulators of muscle cell proliferation determination, whereas myogenin and myf4 act as regulators of muscle cell differentiation (Rudnicki et al. 1993; Steinbacher et al. 2007; Johnston et al. 2008).
MicroRNAs (miRNAs) are short, ∼22 nt, single-stranded RNAs that act as regulators of genes' expression.
Moreover, Zhang et al., [37] proposed that miR-221/222 may act as regulators of the tumor suppressor gene p27Kip1.
