The phrase "a functional study of three" is correct and usable in written English.
It can be used in academic or research contexts when referring to an analysis or examination involving three subjects, items, or cases.
Example: "The research paper presents a functional study of three different teaching methods to evaluate their effectiveness in the classroom."
Alternatives: "an analytical study of three" or "a comparative study of three".
Recently, a functional study of three members of the ApiAP2 family was reported [ 16, 17].
The importance of this methodology and the biological significance of the network proteins were validated by a functional study of three hubs that exhibited variable connectivity, namely, PPA1, SMNDC1, and PI15.
Functional studies of eight P. parasitica GH28 proteins have demonstrated that they are endo-polygalacturonases [ 111, 112].
Here, we report the cloning and functional studies of two IKK homologs, LvIKKβ and LvIKKε, from Pacific white shrimp, Litopenaeus vannamei.
Functional studies of two such mutants – A114P and V289M – in cultured myotubes revealed that, for a given mitochondrial inner membrane potential, the rate of adenine nucleotide exchange was substantially decreased, and, under some conditions, the reversed transport of ATP into mitochondria was predicted to occur readily (Kawamata et al., 2011).
This is in agreement with functional studies of the two tyr duplicates in the rainbow trout [ 22]: simultaneous morpholino knock-down of both paralogs reduces pigmentation in the eye and the skin to the same amount as knocking-down tyr paralogs separately.
Furthermore, the functional studies of the genes connecting two such QTLs show that it is possible to find functions in common for a majority of those genes.
Detailed analyses including functional studies of specific clans in these four fungi that exhibit differential expansion or contraction are currently under investigation.
However, structural and functional studies of AQP1 and GlpF suggest the presence of two constriction sites in the water pore, in addition to the P1-P5 residues, that underlie their high selectivity and efficiency with regard to water or glycerol transport [ 9, 40- 43].
Previous structural and functional studies of Thermus RPS13 showed that there are two structurally important regions where RPS13 interacts with the 16S rRNA [ 27- 29].
Here, we report the cloning and functional studies of proline-rich AMPs (PR-AMPs) from the three species of mud crab: Scylla paramamosain, S. serrata, and the swimming crab Portunus pelagicus.
