Binding of cAMP by an R subunit of PKA occurs in a cooperative fashion; i.e., binding of the first cAMP molecule to CNB-B lowers the Kd for binding of the second cAMP to CNB-A.

Polyglutamylation and polyglycylation are likely mutually exclusive, so they would not normally occur at the same time & both can enhance microtubule stability,
