While similarly robust regulation was not observed in THP-1 cells, our reproducible findings in primary monocytes suggest that SFRS3 might play a physiologic role in the secretion of IL-1β, and that its down-regulation might be required for stronger caspase-1 activation.
Using computational design, we engineered an SspB heterodimer whose subunits did not form homodimers. Experiments with the designed molecule and variants lacking one or two tails demonstrate that both XB modules are required for strong binding and efficient substrate delivery to ClpXP.
Therefore, our results confirm that a narrow range of calcium concentrations is required for strong Lad1/MEKK2 interaction.
In conclusion, N275 and R279 are required for strong binding between CKIε and xDsh, whereas the corresponding chemically distinct residues in CKIα prevent binding of mPer1 to CKIε.
These results suggest that S59 is required for strong activation by protein kinases of the Ca2+-dependent CPK branch, while S120 represents a crucial amino acid for strong activation by the Ca2+-independent branch of the ABA signaling core.
These results suggest that dephosphorylation of ERKs is an important component of their process of action and that coordinated phosphorylation/dephosphorylation is required for strong signaling through this pathway.
RecD, which allows RecBCD DSB-exonuclease activity, is required for strong local but not long-distance hotspotting, indicating that double-strand resection and gap-filling synthesis underlie local hotspotting, and newly illuminating DSB resection in vivo.
Truncation of the entire proline-rich N-terminus region until amino acid 181, giving rise to FOXP3-ΔN, was required for strongest binding to the probe (Figure 5B, lanes 6, 7).
Constructs containing only the central domain (residues 245 502) displayed a weaker interaction with VAB-19ANK, suggesting that although the central domain is sufficient for an interaction, the combination of the PTB and central domains may be required for a strong interaction.
While the single simple techniques provide either diffusion or confusion, respectively, they do not provide both properties, which would be required for a cryptographically strong scheme.
