PKC-zeta-dependent Sp1 Phosphorylation: Regulatory Insights using Novel Phospho-Specific Sp1 Antibodies and Peptide Decoys

点击翻译按钮获取中文摘要

This project will demonstrate the value of novel phospho-specific Sp1 antibodies and phospho-Sp1 peptide decoys as new molecular tools to provide invaluable insights into the regulatory roles of phosphorylated Sp1 in the control of gene expression, an area poorly defined at the present time. These agents will be used to increase our fundamental understanding of Sp1 activity by identifying physiologic agonists of the PKC-zeta-phospho-Sp1 axis and FasL-dependent apoptosis, interactions of phospho-Sp1 with the authentic FasL promoter and its recruitment of collaborative factors. The commercial exploitation of phospho-specific Sp1 antibodies and phospho-Sp1 peptide decoys will generate economic returns to Australia.
