Could play a role in a differentiation signal. The CRINKLY4 (CR4) mutation affects leaf epidermis differentiation such that cell size and morphology are altered, and surface functions are compromised, allowing graft- like fusions between organs.CATALYTIC ACTIVITY:ATP a protein = ADP a phosphoprotein.SIMILARITY:Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.SIMILARITY:Contains 1 protein kinase domain.SIMILARITY:Contains 1 TNFR-Cys repeat."
