"Treatment of ets1 by t-cell nuclear extract or phosphorylation of these four serines by calmodulin-dependent kinase ii (camk ii) has recently been reported to decrease ets1 dna binding by reinforcing autoinhibition"

"Increased Transactivation of the GM-CSF Promoter/Enhancer by Ets1 with Mutated CaMK II Sites | Significantly, phosphorylation of Ets1 by Ca2+-dependent pathways is thought to inhibit DNA binding in vitro. To analyze the role of these four serines, S251, S257, S282, and S285, in transcription, we constructed three mutant derivatives of human Ets1"

"Co-immunoprecipitation analyses and glutathione-S-transferase pull-down assays revealed that ETS1 bound directly to GFI1 via its Ets domain, and GFI1 bound to ETS1 via its zinc-finger domain. Luciferase (Luc) assays using artificial reporters showed that GFI1 repressed ETS1-mediated transcriptional activation and ETS1 repressed GFI1-mediated transcriptional activation, in a dose-dependent manner."

"Full-length c-maf binds to the c-myb and ets-1. / c-maf inhibits c-myb and ets-1 transcriptional activity."

"We demonstrate that p53 and ets-1 coregulate TXSA in an antagonistic and inter-related manner, with ets-1 being a potent transcriptional activator and p53 inhibiting ets-1-dependent transcription. We show that ets-1 and p53 associate physically in vitro and in vivo and that their interaction, rather than a direct binding of p53 to the TXSA promoter, is required for transcriptional repression of TXSA by wild-type p53."

"We found that hgf/sf activates the erk1 map kinase, leading to the phosphorylation of the threonine 38 residue of ets1"

"9-cis retinoid x receptor alpha (rxr alpha) interacted with erk2 but not erk5 in intact cells, whereas ets-1 interacted preferentially with erk5. Increased phosphorylation of rxr alpha and ets-1 was detected in response to 1,25d. Activated erk2 and erk5 specifically phosphorylated rxr alpha and ets-1, respectively.Mutagenesis of ets-1 (t38a) reduced cyp24 promoter activity to levels observed with the dominant-negative mek5(a) and inhibited erk5-directed phosphorylation. Mutated rxr alpha (s260a) inhibited 1,25d-induced cyp24 promoter activity and abolished phosphorylation by activated erk2."

"In this study, we show that Ca(2+) signaling also regulates GM-CSF transcription negatively through Ca(2+)/calmodulin-dependent kinase II (CaMK II) phosphorylation of serines in the autoinhibitory domain for DNA binding of the transcription factor Ets1."
