… allow for a redox regulation of AP- 1 in intact cells. Consistent with this idea is the observation
that treatment of cells with 500 AM H202 did not abolish AP-1 DNA binding, but interfered …

… site, the AP-1-binding site. As the complexity of our knowledge of AP-1 factors has increased,
our … and cell lines deficient in specific AP-1 components. Such studies suggest that different …

… protein 1 (AP-1) complex in protein sorting in intracellular compartments is not yet completely
defined. Here we report that in immature dendritic cells, the β1- and γ-subunits of AP-1 …

… ERα only elicits weak estrogen responses at AP-1 sites in breast cells (12), but ERβ elicits
… AP-1 activity weakly in the presence of estrogens in MCF-7 cells, and ERβ enhanced AP-1 …

… of AP1 from nuclear extracts of HeLa cells. All column fractions were assayed for AP-1 by …
of affinity-purified AP-1 visualized by staining with silver. The left lane displays the pattern of …

… -1’s reactivity at the intact AP site or a pre-incised AP site. We next examined purified PARP-1
cross-linking with a linear DNA containing either an intact AP site or pre-incised AP site; in …

… to show that AP-1 activity is inhibitable by coexpression of GSK-3 in intact cells. Furthermore…
to similar regulation by GSK-3 in intact cells. Comparison of tryptic phosphopeptide maps of …
