Previous studies have demonstrated that efficient splicing of the primary transcript of the yeast MER2 gene requires the MER1 protein, which is produced only in meiotic cells. A genetic selection was devised to recover second-site mutations that bypass the requirement for MER1 in MER2 RNA-splicing. This selection identified a mutation in SNR19, the gene for(More)
Interleukin-8 (IL-8) is a dimeric, C-X-C chemokine, produced by a variety of cells and which elicits proinflammatory responses from the neutrophil. As a prelude to drug design, we have investigated the interactions between IL-8 and its receptor by preparing a number of single-site mutants of IL-8 and determining their activity in receptor-binding and(More)
Ecdysteroids play an important role in regulating development and reproduction in insects. Interaction of 20-hydroxyecdysone (20E) with ecdysone receptor (EcR) as a heterodimer with ultraspiracle (USP) protein triggers the activation of 20E-responsive genes. In this paper we describe a ligand-mediated transactivation system in yeast using the spruce budworm(More)
In many land plants, the stomatal pore opens during the day and closes during the night. Thus, periods of darkness could be effective in decreasing pathogen penetration into leaves through stomata, the primary sites for infection by many pathogens. Pseudomonas syringae pv. tomato (Pst) DC3000 produces coronatine (COR) and opens stomata, raising an(More)
Breast tumours progress from hyperplasia to ductal carcinoma in situ (DCIS) and invasive breast carcinoma (IBC). PRH/HHEX (proline-rich homeodomain/haematopoietically expressed homeobox) is a transcription factor that displays both tumour suppressor and oncogenic activity in different disease contexts; however, the role of PRH in breast cancer is poorly(More)
Human integrase interactor 1 (INI1/SMARCB1/SNF5) is a chromatin-remodeling molecule that binds to HIV-1 integrase and enhances proviral DNA integration. INI1 is also known as a tumor suppressor gene and has been found to be mutated in several aggressive tumors such as rhabdoid and lymphoid tumors. To study the function of simian INI1, we screened and cloned(More)
