Activation of protein kinase C decreases phosphorylation of c-Jun at sites that negatively regulate its DNA-binding activity

WJ Boyle, T Smeal, LHK Defize, P Angel, JR Woodgett… - Cell, 1991 - cell.com
In resting human epithelial and fibroblastic cells, c-Jun is phosphorylated on serine and
threonine at five sites, three of which are phosphorylated in vitro by glycogen synthase …

Phorbol esters stimulate the phosphorylation of c-Jun but not v-Jun: regulation by the N-terminal delta domain.

V Adler, CC Franklin, AS Kraft - Proceedings of the National …, 1992 - National Acad Sciences
c-Jun and its oncogenic counterpart v-Jun are completely conserved within the region from
