Mechanisms underlying nonsteroidal anti-inflammatory drug-induced p27(Kip1) expression.

abstract：:The sulfoconjugation of tyrosyl residues is a widespread post-translational modification of biologically active proteins and peptides. The rat liver Golgi enzyme tyrosylprotein sulfotransferase has previously been shown to catalyze the transfer of a sulfate moiety from 5'-phosphoadenosine-3'-phosphosulfate to the synt...
