The phrase "a interacts with" is correct and usable in written English.
It can be used in contexts where you are describing the relationship or connection between two entities, such as in scientific, technical, or social discussions.
Example: "In this experiment, a interacts with b to produce a significant reaction."
Alternatives: "a engages with" or "a connects with".
On the other hand, if proteins from both families duplicate, the edges representing the interactions do not necessarily overlap: e.g. if A' interacts with B' and A" interacts with B" and A' does not interact with B" and A" does not interact with B'.
Upon activation, Rho A interacts with and activates the Rho A-dependent kinase (ROCK).
To test whether Staphopain A interacts with neutrophils, we used a multi-screening assay for surface-expressed receptors on human neutrophils.
However, to ensure consistency in defining symmetric interactions (if A interacts with B, it follows that B interacts with A), we ordered the features such that the smaller value always came first.
S200 is part of a loop that forms critical interactions with the helix: R49 on helix A interacts with R201, the interaction being further stabilized by E203 (Fischmann et al., 2009).
But think about it: As I develop the x-ray blot, I discover that protein A interacts with protein B; this interaction has implications in some severe human disease.
In the present study, our in silico analysis showed that bacosides (A3, A) interact with TPH.
Third, Aurora-A interacts with the CUL3-KLHL18 ligase through direct interaction with KLHL18.
In LDCV secretion, Granuphilin/Slp4-a interacts with both Munc18-1 and Rab3a in pancreatic β-cells [22].
We conclude from these data that under ER stress CN-A interacts with PERK and this association appears to increase phosphorylation of PERK.
It will be interesting to learn if PUM2 competes or cooperates with the other, previously identified activators or destabilization factors of Aurora-A, and if Aurora-A interacts with more than one regulator at a time.
