The phrase "a proxy for functional" is correct and usable in written English.
It can be used in contexts where you want to indicate that something serves as a substitute or representation for a functional aspect or characteristic.
Example: "In this study, we used user engagement as a proxy for functional performance in the application."
Alternatives: "a substitute for functional" or "a stand-in for functional".
As a proxy for functional variability, similarities and differences between the protein sequence of OR genes are often used [7], [14].
Based on the view that sub-family classification is a proxy for functional similarity, the lack of human OR gene orthologs to either of the two subfamilies would indicate that humans cannot detect Iva.
Fold expansion can be considered a proxy for functional sophistication, where 100% represents the current level of sophistication.
We next addressed the expression location of newly isolated SCD shark genes, as a proxy for functional appraisal.
Conserved elements in noncoding sequences can be used as a proxy for functional regulatory motifs in flanking regions surrounding CDS.
The highest level of dependency within the year before the index date was included as a proxy for functional and cognitive impairments.
Given that the main reason for the heterogeneity of evolutionary rates among sites seems to be differences in their selective constraints (due to the functional and/or structural requirements of the gene), we herein used the shape parameter α as a proxy for the functional restriction of each studied protein.
For these reasons most current studies use mRNA expression levels as a proxy for estimating functional differences that occur at the protein level.
Even though mRNA expression levels are commonly used as a proxy for estimating functional differences that occur at the protein level, the relation between mRNA and protein expression is not well established.
However, by using a related model organism as a proxy for missing functional genomic data and applying multiple layers of subtractive filters based on comparative sequence analysis, we can pre-validate a pool of targets to facilitate their entry into drug discovery programs.
We used the understanding of written information as a proxy for low functional HL.
