The phrase "appear to be functionally" is correct and usable in written English.
It can be used when describing something that seems to have a particular function or role, often in a technical or analytical context.
Example: "The components of the machine appear to be functionally integrated, allowing for seamless operation."
Alternatives: "seem to be operationally" or "seem to serve a functional".
Thus, like the Hedgehog pathway in Drosophila, CDK9 (P-TEFb) and CDK11 appear to be functionally linked for Tat function.
In contrast to some of RPGRIP1 partners, the RPGRIP1-dependent subcellular processes appear to be functionally redundant for kidney function (Mollet et al., 2002; Otto et al., 2002; Wiik et al., 2008; Won et al., 2009; Won et al., 2011).
Moreover, the endogenous Totivirus-like genes appear to be functionally maintained with non-viral functions and may have been further transferred between deeper yeast lineages.
While most nsSNPs appear to be functionally neutral, the others affect protein function and may cause or influence diseases.
However, the two loss-of-function mutations at Dw3 appear to be functionally equivalent, because family D is segregating for both of them and does not have a Dw3 QTL.
These findings suggest that the CT bellies appear to be functionally designed for different motor tasks.
Both states appear to be functionally important because proteins involved in the assembly or transfer of Fe-S clusters have been shown to interact preferentially with either the S or D state of IscU.
Bilateral regions of the intraparietal sulcus (IPS) appear to be functionally selective for both rudimentary non-symbolic number tasks and higher-level symbolic number tasks in adults and older children.
cV1q, a neutralizing rat/mouse chimeric anti-mouse tumor necrosis factor (TNF) monoclonal antibody (mAb), and Rt108, a neutralizing mouse anti-rat TNF (anti-raTNF) mAb, appear to be functionally monovalent for TNF-binding despite containing two antigen binding sites.
The hogs appear to be functionally bereft of higher cortical layers of the brain that in other animals are associated with rationality and intelligence; which makes them a much more dangerous farmyard animal than they had hitherto been believed to be.
Albeit different in their expression patterns, Axin and Axin2 appear to be functionally, at least partly, interchangeable in canonical Wnt pathway (Chia and Costantini, 2005).
