Model for phosphorylation-induced dissociation of the β4-plectin complex. Phosphorylation of β4 on T1736 by PKD1 or other CAMK-like kinases results in the dissociation of the C-tail and the plakin domain of plectin, whereas phosphorylation of β4 at S1356 and S1364 by ERK1/2 and p90RSK1/2 causes a loss of plectin-ABD binding. Subsequent binding of plectin to F-actin or Ca2+/calmodulin may shift the equilibrium toward complete disassociation of the β4-plectin complex.
