Table 3. Knockout experiment.
Input | Block | Effect/molecular dependence |
---|---|---|
Calcium 2000 nM for 1 s |
KCK | CaMKII is activated but cannot autophosphorylate itself, thus RasGRF is the only contributor |
KSyn1 | pCaMKII is unable to bind to SynGap | |
KSyn2 | pCaMKII binds to SynGap but is unable to phosphorylate SynGap | |
KSyn3 | SynGap is phosphorylated but is unable to disperse to the dendrite | |
cAMP 500 nM for 30 s |
KEpac | Epac binds cAMP but cannot activate Rap1GDP, thus PKA is the only contributor |
KPKA | Final step of PKA pathway activation of Rap1GDP is blocked, thus Epac is the only contributor |
