The phrase "act as a regulator of" is correct and usable in written English.
It can be used in contexts where you are describing the function or role of something in controlling or managing a particular process or system.
Example: "The enzyme acts as a regulator of metabolic pathways, ensuring that energy production is balanced."
Alternatives: "serve as a controller of" or "function as a moderator of".
NDRG2 was found to act as a regulator of myoblast proliferation and can be regulated by anabolic and catabolic factors [ 8].
NO was found to act as a regulator of pressure-natriuresis and plays an important role in the regulation of blood flow to the renal medulla and in the tubular regulation of sodium excretion [56].
hnRNPI/PTB1 can act as a regulator of 3′end processing efficiency upon binding to cis-acting RNA sequence elements playing a role in polyadenylation, such as the upstream sequence element (USE) and the DSE (Blechingberg et al, 2007b; Castelo-Branco et al, 2004; Danckwardt et al, 2011; Hall-Pogar et al, 2007; Millevoi et al, 2009).
