The phlebotomine sandfly, Lutzomyia longipalpis, a major vector of the Leishmania parasite, uses terpene pheromones to attract conspecifics for mating. Examination of the L. longipalpis genome revealed a putative terpene synthase (TPS), which—upon he...

Leishmaniasis is a debilitating and often fatal neglected tropical disease. Males from sub-populations of the Leishmania-harbouring sandfly, Lutzomyia longipalpis, produce the diterpene sex and aggregation pheromone, sobralene, for which geranylgeran...

The Small Molecule Antagonist KCI807 Disrupts Association of the Amino-Terminal Domain of the Androgen Receptor with ELK1 by Modulating the Adjacent DNA Binding Domain. Molecular Pharmacology, 103(4), 211-220. https://doi.org/10.1124/molpharm.122.000589

The androgen receptor (AR) is a crucial coactivator of ELK1 for prostate cancer (PCa) growth, associating with ELK1 through two peptide segments (358-457 and 514-557) within the amino-terminal domain (NTD) of AR. The small-molecule antagonist 5-hydro...

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.

Identification of ELK1 interacting peptide segments in the androgen receptor (2022)
Journal Article

Prostate cancer (PCa) growth requires tethering of the androgen receptor (AR) to chromatin by the ETS domain transcription factor ELK1 to coactivate critical cell proliferation genes. Disruption of the ELK1–AR complex is a validated potential means o... Read More about Identification of ELK1 interacting peptide segments in the androgen receptor.

Ubiquitin-Mediated Control of ETS Transcription Factors: Roles in Cancer and Development (2021)

Genome expansion, whole genome and gene duplication events during metazoan evolution produced an extensive family of ETS genes whose members express transcription factors with a conserved winged helix-turn-helix DNA-binding domain. Unravelling their... Read More about Ubiquitin-Mediated Control of ETS Transcription Factors: Roles in Cancer and Development.

ELK-1 ubiquitination status and transcriptional activity are modulated independently of F-Box protein FBXO25 (2021)

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.

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.
