Activation of Akt requires the phosphorylation of Ser473 within the carboxyl-terminal hydrophobic motif, which primarily facilitates the phosphorylation of Thr308 in the activation loop to fully activate Akt kinase activity [12].
Upon recruitment to the cell membrane AKT is phosphorylated at two critical residues, T308 in the activation T loop, and S473 in the hydrophobic domain, to fully activate its kinase activity.
RAC is activated in proximity to p110β and binds to the RBD to fully activate p110β lipid kinase activity (schematic in Figure 6F).
Activated SYK phosphorylates BLNK, thereby leading to the formation of BCR signalosome to fully activate the downstream PI3K, mitogen-activated protein kinase (MAPK), and NF- κB pathways [ 26].
According to the currently accepted model of T cell activation, two signals are required to fully activate resting naïve T lymphocytes.
15, 18 QFM weakness related to OA may stem from voluntary activation failure (ie, an inability to fully activate the QFM) and/or muscle atrophy.
The experiments used macrophages obtained from genetically engineered mice and found that the direct activation of SFK proteins alone does not fully activate signaling pathways in the macrophages.
Ube2S keeps APC partially active during mitotic arrest and is required to fully activate APC-Cdc20 (Garnett et al., 2009).
These observations indicated that ectopic PAP1 overexpression by itself did not fully activate all rate limiting steps of anthocyanin biosynthesis, and further activation of the phenylpropanoid pathway required additional environmental signals.
Addition of 2 mM Ca2+ was sufficient to fully activate R580A-TG2 (approximately 8 fold over vector control) and increase transamidating activity in the lysates of Y516F-TG2 transfecellscells approximately 3 fold over vector control.
However, κB and GATA factors alone were not sufficient for MsMoricin gene activation, suggesting that other co-regulators may be required to fully activate AMP genes.
