The phrase "acting at different steps" is correct and usable in written English.
It can be used to describe the process of taking action or making decisions at various stages of a procedure or project.
Example: "In the project, we will be acting at different steps to ensure that all aspects are covered effectively."
Alternatives: "taking action at various stages" or "performing tasks at different phases".
Mutations in autophagy genes acting at different steps of autophagosome formation and maturation cause an increased number of cell corpses.
To gain insights into the molecular mechanisms of elevated markers of autophagy induced by CPTH6 treatment, we silenced the expression of several proteins acting at different steps of autophagy.
The action of miRNAs in translation repression appears to involve various molecular mechanisms acting at different steps of the initiation stage or at the elongation stage (reviewed in Filipowicz et al, 2008; Wu and Belasco, 2008).
Mitochondrial dysfunction is associated with different environmental influences or certain genetic conditions, and can be artificially induced by inhibitors acting at different steps of the mitochondrial electron transport chain (ETC).
These cells have important vascular-modulatory functions and also appear to facilitate the establishment of metastasis by acting at different steps during the metastatic cascade (Qian & Pollard, 2010; Mazzieri et al, 2011).
Since the insulator protein CTCF plays an essential role in regulation of gene expression, we analyzed the transcript levels of components acting at different steps in ecdysone signaling pathway.
Many EDCs are reactive chemicals that exhibit multiple mechanisms of toxicity by acting at different sites within the body.
