Overlapping promoter targeting by Elk-1 and other divergent ETS-domain transcription factor family members
ETS-domain transcription factors play important roles in controlling gene expression in a variety of different contexts; however, these proteins bind to very similar sites and it is unclear how in vivo specificity is achieved. In silico analysis is unlikely to reveal specific targets for individual family members and direct experimental approaches are therefore required. Here, we take advantage...
متن کاملThe Elk-1 ETS-domain transcription factor contains a mitogen-activated protein kinase targeting motif.
The phosphorylation of transcription factors by mitogen-activated protein kinases (MAP) is a pivotal event in the cellular response to the activation of MAP kinase signal transduction pathways. Mitogenic and stress stimuli activate different pathways and lead to the activation of distinct groups of target proteins. Elk-1 is targeted by three distinct MAP kinase pathways. In this study, we demon...
متن کاملDifferential targeting of MAP kinases to the ETS-domain transcription factor Elk-1.
The activation of MAP kinase (MAPK) signal transduction pathways results in the phosphorylation of transcription factors by the terminal kinases in these cascades. Different pathways are activated by mitogenic and stress stimuli, which lead to the activation of distinct groups of target proteins. The ETS-domain transcription factor Elk-1 is a substrate for three distinct classes of MAPKs. Elk-1...
متن کاملEpidermal growth factor-mediated activation of the ETS domain transcription factor Elk-1 requires nuclear calcium.
Cytosolic and nuclear Ca(2+) have been shown to differentially regulate transcription. However, the impact of spatially distinct Ca(2+) signals on mitogen-activated protein kinase-mediated gene expression remains unknown. Here we investigated the role of nuclear and cytosolic Ca(2+) signals in epidermal growth factor (EGF)-induced transactivation of the ternary complex factor Elk-1 using a GAL4...
متن کاملThe mechanism of phosphorylation-inducible activation of the ETS-domain transcription factor Elk-1.
Protein phosphorylation represents one of the major mechanisms for transcription factor activation. Here we demonstrate a molecular mechanism by which phosphorylation by mitogen-activated protein (MAP) kinases leads to changes in transcription factor activity. MAP kinases stimulate DNA binding and transcriptional activation mediated by the mammalian ETS-domain transcription factor Elk-1. Phosph...
