Comparative analysis of protein expression systems and PTM landscape in the study of transcription factor ELK-1 (2022)
Journal Article
Ducker, C., Ratnam, M., Shaw, P. E., & Layfield, R. (2023). Comparative analysis of protein expression systems and PTM landscape in the study of transcription factor ELK-1. Protein Expression and Purification, 203, Article 106216. https://doi.org/10.1016/j.pep.2022.106216

Post-translational modifications (PTMs) are important for protein folding and activity, and the ability to recreate physiologically relevant PTM profiles on recombinantly-expressed proteins is vital for meaningful functional analysis. The ETS transcr... Read More about Comparative analysis of protein expression systems and PTM landscape in the study of transcription factor ELK-1.

ELK-1 ubiquitination status and transcriptional activity are modulated independently of F-Box protein FBXO25 (2021)
Journal Article
Quintero-Barceinas, R. S., Gehringer, F., Ducker, C., Saxton, J., & Shaw, P. E. (2021). ELK-1 ubiquitination status and transcriptional activity are modulated independently of F-Box protein FBXO25. Journal of Biological Chemistry, 296, Article 100214. https://doi.org/10.1074/jbc.ra120.014616

The mitogen-responsive, ETS-domain transcription factor ELK-1 stimulates the expression of immediate early genes at the onset of the cell cycle and participates in early developmental programming. ELK-1 is subject to multiple levels of posttranslatio... Read More about ELK-1 ubiquitination status and transcriptional activity are modulated independently of F-Box protein FBXO25.

USP17-mediated de-ubiquitination and cancer: Clients cluster around the cell cycle (2020)
Journal Article
Ducker, C., & Shaw, P. E. (2021). USP17-mediated de-ubiquitination and cancer: Clients cluster around the cell cycle. International Journal of Biochemistry and Cell Biology, 130, Article 105886. https://doi.org/10.1016/j.biocel.2020.105886

Eukaryotic cells perform a range of complex processes, some essential for life, others specific to cell type, all of which are governed by post-translational modifications of proteins. Among the repertoire of dynamic protein modifications, ubiquitina... Read More about USP17-mediated de-ubiquitination and cancer: Clients cluster around the cell cycle.

De-ubiquitination of ELK-1 by USP17 potentiates mitogenic gene expression and cell proliferation (2019)
Journal Article
Ducker, C., Chow, L., Saxton, J., Handwerger, J., McGregor, A., Strahl, T., …Shaw, P. E. (2019). De-ubiquitination of ELK-1 by USP17 potentiates mitogenic gene expression and cell proliferation. Nucleic Acids Research, 47(9), 4495-4508. https://doi.org/10.1093/nar/gkz166

ELK-1 is a transcription factor involved in ERK-induced cellular proliferation. Here we show that its transcriptional activity is modulated by ubiquitination at lysine 35 (K35). The level of ubiquitinated ELK-1 rises in mitogen-deprived cells and fal... Read More about De-ubiquitination of ELK-1 by USP17 potentiates mitogenic gene expression and cell proliferation.

Strategy for tumor selective disruption of androgen receptor function in the spectrum of prostate cancer (2018)
Journal Article
Rosati, R., Polin, L. A., Ducker, C., Li, J., Bao, X., Selvakumar, D., …Ratnam, M. (2018). Strategy for tumor selective disruption of androgen receptor function in the spectrum of prostate cancer. Clinical Cancer Research, https://doi.org/10.1158/1078-0432.ccr-18-0982

Purpose: Testosterone suppression in prostate cancer (PC) is limited by serious side effects and resistance via restoration of androgen receptor (AR) functionality. ELK1 is required for ARdependent growth in various hormone-dependent and castration r...

Stepwise evolution of Elk-1 in early deuterostomes (2016)
Journal Article
Saxton, J., Ferjentsik, Z., Ducker, C., & Shaw, P. E. (in press). Stepwise evolution of Elk-1 in early deuterostomes. FEBS Journal, 283(6), https://doi.org/10.1111/febs.13607

Metazoans have multiple ETS paralogues with overlapping or indiscriminate biological functions. Elk- 1, one of three mammalian Ternary Complex Factors (TCFs), is a well-conserved, ETS domain-containing transcriptional regulator of mitogen-responsive...
