To overcome this limitation of Cre/LoxP-mediated DNA-recombination, we added a second dimension of recombination control by designing a novel "split-Cre" system based on the complementation of Cre protein fragments.
Further live-cell screening methods include two-hybrid screens [ 4] or assays based on the complementation of fluorescent proteins [ 5].
Since our study focused on the complementation of different data sources, an important question concerning definitions of chronic conditions remained unanswered: How arbitrary are the definitions of chronic health conditions based on cut-off-values, for instance dyslipidemia?
Regardless of which domain is responsible for the catalysis, we conclude that all four of these double-length PurE-like proteins effect the AIR carboxylase reaction alone on the basis of the complementation results with the M. smithii and M. thermoautotrophicus genes.
Among the nine PpCOP1 genes, we chose the one with the highest sequence similarity to AtCOP1, based on BLAST scores, for the complementation study (Pp1s135_17V6.1, PpCOP1a, Figure 1).
This is a good example on how the complementation of theoretical and experimental approaches represents a valuable approach for the analysis of the molecular recognition properties of GAG protein systems.
On the other hand, the complementation will be done with no prompt if selected.
This bacterial two-hybrid system is based on the functional complementation between two complementary fragments, T25 and T18, of the catalytic domain of CyaA, in an E. coli cya strain.
In this study, the effect of cytoplasmic modifications of the A3AR on βarr2 recruitment was evaluated in transiently transfected HEK293T cells, using a live-cell split-reporter system (NanoBit®, Promega), based on the structural complementation of NanoLuc luciferase, allowing real-time βarr2 monitoring.
Following this rational, we recently developed the "split-Cre system" based on the functional complementation of Cre protein fragments [15].
DiCre is based on the functional complementation, using ligand-induced dimerization [25], of two inactive Cre moieties that can be associated by rapamycin through cross-linking the protein fragments FKBP12 (FK506-binding protein; [26]) and FRB, the ligand binding domain of FRAP (FKBP12-rapamycin associated protein; [27]) linked to the Cre moieties.
