The phrase "as a functional marker" is correct and usable in written English.
It can be used in linguistic or grammatical discussions to refer to a word or phrase that serves a specific grammatical function in a sentence.
Example: "In this context, the word 'however' acts as a functional marker to indicate a contrast between the two statements."
Alternatives: "as a grammatical indicator" or "as a structural signal".
Evidence from psychopathology and pharmacological manipulations indicates that spontaneous EBR may serve as a functional marker of central/tonic DA function (Colzato, van Wouwe, & Hommel, 2007; Taylor et al., 1999), may also show sensitivity to positive mood induction (Akbari Chermahini & Hommel, 2012).

The laccase gene was used as a functional marker due to its involvement in lignocellulose degradation.

Therefore, ALDH1 not only serves as a functional marker of CSCs, but also plays important role in resistance to chemotherapy.
As a functional marker of renal dysfunction, the level of creatinine in plasma was significantly elevated in Nx rats (Table 2; p < 0.01).
Firstly, reproducibility of a functional marker such as FMD is low as compared to most biochemical markers.
Thirdly, miR1511-InDel is a functional marker as miRNAs play in functional roles in the regulation of gene expression at the post-transcriptional level in eukaryotes and viruses [ 26, 36].
Assessment of mHLA-DR expression was thus proposed to serve as a "global" functional marker of immune function [4, 5, 7, 12].
PIV thus can be viewed as a surrogate functional marker, allowing a simple and non-invasive assessment of the integrity of a physiological mechanism involving post-ischemia acidification-induced hyperemia, a necessary condition to allow the normal skin to resist to pressure ulcer.
These results provide a reference for miRNA1511-InDel as a new functional marker type for the study of genetic diversity, gene mapping and molecular breeding.
