Although the functional impact of ck-mediated atf1 phosphorylation is still unclear, we found that mutation of ser-36 and ser-41 increased cbp kix domain binding by up to four fold (fig. 2g). This result is consistent with the negative impact of ck-mediated phosphorylation on cbp binding affinity of creb that we previously reported |

These data suggested that atf1 is always hyperphosphorylated on the ck sites in vivo. Also, the antibody reactivity suggested that in addition to ser-36 and ser-41, ser-38 and ser-44 were phosphorylated in vivo. To accommodate these findings, we propose that constitutive hyperphosphorylation by ck1/ck2 maintains atf1 in an inactive state that promotes transcriptional repression. |
