The phrase "acts as target" is correct and usable in written English.
It can be used in contexts where you are describing something that serves as a goal or objective for an action or process.
Example: "In this experiment, the chemical compound acts as target for the reaction, allowing us to observe the changes more clearly."
Alternatives: "serves as a target" or "functions as a target".
The density profile of the ISM perpendicular to the galactic plane, which acts as target material for hadronic gamma-ray production, drops quite fast with increasing distance.
It has been shown that HP1γ, which plays an important role in heterochromatin formation, acts as target protein of PIM-1, and we hypothesized that besides of effecting DNA damage response, PIM-1 also can potentially affect heterochromatin formation by interacting with and phosphorylating HP1γ protein.
The identified amino acid residues can act as target sites for the design and development of drug candidates against mPGES-1.
Both natural and modified CRDs can be used as probes for detecting and isolating glycoproteins that bear specific glycan epitopes and that act as target ligands for glycan-binding receptors.
HSV-2-activated CD4+ T cells can act as target cells for HIV, facilitating HIV acquisition.
Cruciforms may act as target sites for activator and repressor proteins and serve as a novel mechanism that controls cell-specific promoter activity [23].
The cells can act as target cells that respond to exposure to a variety of inflammatory mediators and cytokines by altering one or several of their functions, such as mucin secretion or ion transport [6].
It is possible that sense transcripts may act as target mimicry molecules that sequester sRNAs, asRNAs, or ribonucleases from their respective mRNA target domains [ 5].
The tumor stroma itself appears to be a potential target for immunotherapy due to the over-expression of certain proteins that can act as target structures.
AtIPS1 and At4 have been shown to act as target mimics of miR399 by binding and sequestering miR399 and reduce miR399-mediated cleavage of PHO2 which is important for phosphate uptake [ 22, 23].
In mice injected with silica, histological evidence of the compensatory proliferation of macrophages suggests that precursors of these cells may act as target cells for the virus and that this may override any immunosuppressive response effected by the silica.
