Description

The abstract establishes CaMKII/CaN-PP1 as a calcium-dependent switch controlling growth cone direction but doesn’t explain how these enzymes mechanistically produce opposite turning behaviors. Understanding these downstream effectors is critical for manipulating axon guidance in regenerative therapies.
