abstract = {Microtubule associated protein 2 (MAP2) interacts with the
regulatory protein 14-3-3ζ in a cAMP-dependent protein
kinase (PKA) phosphorylation dependent manner. Using
selective phosphorylation, calorimetry, nuclear magnetic
resonance, chemical crosslinking, and X-ray crystallography,
we characterized interactions of 14-3-3ζ with various
binding regions of MAP2c. Although PKA phosphorylation
increases the affinity of MAP2c for 14-3-3ζ in the proline
rich region and C-terminal domain, unphosphorylated MAP2c
also binds the dimeric 14-3-3ζ via its microtubule binding
domain and variable central domain. Monomerization of
14-3-3ζ leads to the loss of affinity for the
unphosphorylated residues. In neuroblastoma cell extract,
MAP2c is heavily phosphorylated by PKA and the proline
kinase ERK2. Although 14-3-3ζ dimer or monomer do not
interact with the residues phosphorylated by ERK2, ERK2
phosphorylation of MAP2c in the C-terminal domain reduces
the binding of MAP2c to both oligomeric variants of
14-3-3ζ.},
