Activation of ternary complex factor Elk-1 by stress-activated protein kinases
BACKGROUND The mammalian response to stress results in the activation of stress-activated protein kinases (also known as cJun N-terminal kinases; SAPKs or JNKs), which are a sub-group of the mitogen-activated protein (MAP) kinase family. The SAPKs are involved in the upregulation of activity of the transcription factor AP-1 by post-translational modification of two of its components, cJun and A...
متن کاملDimer formation by ternary complex factor ELK-1.
Ternary complex factors (TCFs), a subgroup of the ets protein family, bind with a dimer of serum response factor to the c-fos serum response element. Both DNA binding and transcriptional activation by TCFs are regulated by mitogen-activated protein kinases. When activated, mitogen-activated protein kinases form homodimers that translocate to the nucleus, where they interact with TCFs via specif...
متن کاملActivation of the human T-cell leukemia virus type 1 long terminal repeat by the ternary complex factor Elk-1.
Serum response factor (SRF) was recently shown to bind and activate the human T-cell leukemia virus type 1 (HTLV-1) promoter at bases -116 to -125 relative to the transcription start site. In addition to the SRF binding site (CArG box), serum response elements (SRE) also typically contain a binding site for a member of the ternary complex factor (TCF) family. Here we demonstrate the presence of...
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 کاملMitogen-induced recruitment of ERK and MSK to SRE promoter complexes by ternary complex factor Elk-1
Many eukaryotic genes are acutely regulated by extra-cellular signals. The c-fos serum response element (SRE) mediates transcriptional activation in response to mitogens through serum response factor (SRF)-dependent recruitment of Elk-1, a mitogen-activated protein kinase (MAPK)-responsive transcription factor. How subsequent events at SRE promoters stimulate initiation of transcription has yet...
