function:May be the important intermediate by which p53 mediates its role as an inhibitor of cellular proliferation in response to DNA damage. Binds to and inhibits cyclin-dependent kinase activity , preventing phosphorylation of critical cyclin-dependent kinase substrates and blocking cell cycle progression. ,induction:By p53 , mezerein (antileukemic compound) and interferon beta. ,PTM:Phosphorylation of Thr-145 by Akt or of Ser-146 by PKC impairs binding to PCNA. ,similarity:Belongs to the CDI family. ,tissue specificity:Expressed in all adult human tissues , with 5-fold lower levels observed in the brain. ,
