tokens: Further analysis reveals that the inducible phosphorylation of I kappa B alpha maps to two serines in the N terminus of the protein ( residues 32 and 36 ) and that the mutation of either residue is sufficient to abolish ligand-induced degradation , whereas both residues must be mutated to abolish inducible phosphorylation of the protein .
