The phrase "a preferential interaction of" is correct and usable in written English.
It can be used in contexts discussing relationships or interactions that are favored or prioritized in a particular situation or study.
Example: "The researchers observed a preferential interaction of the two proteins, which enhanced their binding affinity."
Alternatives: "a favored interaction of" or "a prioritized interaction of".
A preferential interaction of the nickel with niobia was observed in both niobia silica samples.
Although the extended conformation of anandamide is consistent with an interaction with phospholipids [4], the perfect fit between cholesterol and anandamide suggested a preferential interaction of anandamide with cholesterol rather than with phosphatidylcholine.
This in silico analysis demonstrated a preferential interaction of mitogen- and stress-activated kinase-1 (MSK1) with non-acetylated histone H3 compared to K9- and K14-acetylated H3.
Consistent with these observations, Parnas et al. (Parnas et al. 2010) found a preferential interaction of Elg1 with sumoylated PCNA, mediated by three SIMs and a motif distantly related to the PIP box in the N-terminal domain of Elg1.
A number of researchers reported a preferential interaction of C1orf124 with ubiquitylated PCNA (Centore et al. 2012; Ghosal et al. 2012; Juhasz et al. 2012) and observed that its recruitment to damage-induced foci was dependent on Rad18 (Centore et al. 2012; Juhasz et al. 2012; Machida et al. 2012) or even K164 of PCNA (Machida et al. 2012).
The identification of a procaspase-specific binding surface on the FADD DED suggests a preferential interaction with one, but not both, of the DEDs of procaspase-8 in a perpendicular arrangement.
Even in vitro studies suggesting a preferential interaction might be misleading in the absence of firm genetic evidence linking the conjugation of the modifier to the action of the reader.
Early work indicated a preferential interaction between PDZ domains and the C-terminal amino acids of target proteins [ 4].
We conclude that the chances of discovering life-saving treatments are directly related to the richness of social interactions between researchers inherent in a preferential interaction model.
Comparative assays using a series of transiently overexpressed HDACs have also suggested a preferential interaction between Smad7 and HDAC-1 or HDAC-3 (Simonsson et al., 2005).
Nap1 and Htz1 show a preferential interaction with AG-rich DNA sequences.
