KT 5720 has been used as a chemical inhibitor of cell signaling pathway. It has also been used as a protein kinase A (PKA) inhibitor to study its effect on the nuclear import of CRTC1 in α-MSH-activated B16-F0 cells and on COX-2 stimulation of tumor-associated Vascular endothelial growth factor (VEGF) expression.
Biochem/physiol Actions
Specific, cell-permeable inhibitor of protein kinase A (PKA). No significant effect on protein kinase C (PKC), protein kinase G (PKG) or myosin light chain kinase (MLCK).

Correct guidance of axons to their targets depends on an intricate network of signaling molecules in the growth cone. Calcium and cAMP are two key regulators of whether axons are attracted or repelled by molecular gradients, but how these molecules

The capacity for long-term changes in synaptic efficacy can be altered by prior synaptic activity, a process known as "metaplasticity." Activation of receptors for modulatory neurotransmitters can trigger downstream signaling cascades that persist beyond initial receptor activation and may thus
