Example: "The ability to adapt to changing environments is a defining function for successful species in nature."
Alternatives: "a key role in" or "an essential aspect of".
The evolutionary conservation of the DUX4 ORF since placental mammals and the presence of several functional paralogues in rodents lend support to a defined function for double homeodomain proteins [25].
The fact that CIDs subclasses are maintained in early lineages suggest that a presumed interference between duplicates was resolved, and a defined function for each subclass was achieved.
The question of whether the extracellular enzymatic activity of CD38 is related to a defined function or, for example is a vestigial remain of a previous function, is not resolved.
In particular, we give a presentation of the sum begin{aligned} sum _{left| mathbf {k}right| =n}left[ prod _{i=1}^{r}genfrac{0.0pt}0{ ck_{i}-a_{i}}{k_{i}}right] end{aligned}as a derivative of an explicitly defined function, for arbitrary (cin mathbb {R}) and (mathbf {a}=left( a_{1},ldots, a_{r}right) in mathbb {R} ^{r}).
> BLASTX analyses of the 5123 EST sequences suggested a nearly defined function for ∼71.5% of ILP markers, and 28.5% had no similarities to previously sequenced genes.
Having a source of pure human brain αSyn could allow studies of its interactions with various membrane lipids and proteins, thus elucidating a more clearly defined function for the protein and better differentiating physiological from pathological activities.
The direct methods enhance the details by defining a function for contrast [1, 12, 13].
This is the first study to define a function for increased BP1 expression in breast cancer and to highlight pathways important for further exploration.
