"functional domain" is a correct phrase which can be used in written English.
Example: The functional domain of this system is to accurately track patient data over time.
b Molecular function associated with the functional domain.
arjN functionally complements the asrij null mutant, indicating that the OCIA domain is the functional domain.
Orthology and functional domain conservation of cortex protein.
Box fill colours denote orthology/homology and functional domain conservation.
Phylogenetic distribution of DEG with different patterns of functional domain conservation.
The protein sequence and functional information of DEGs were obtained from UniProt database73 or InterProScan tool for functional domain identification74.
The Ubx and bxd transcription units comprise a single functional domain in the bithorax complex of Drosophila melanogaster.
The eBLOCKs database enumerates a cascade of protein blocks with varied conservation levels for each functional domain.
Changes in gene function may also cause phenotypic innovation, and such changes could be evident from changes in the functional domain architecture of proteins.
The phylogenies were annotated with the functional domain architectures of the proteins using SMART56, which provided additional evidence for evaluation of orthology.
The posterior probabilities of tree nodes are indicated by colored dots and the trees are annotated with the functional domain architecture of the proteins, as determined with SMART32.
