We constructed a double-stranded plasmid containing a single cis, syn-cyclobutane thymine dimer (T[c,s]T) 385 base pairs from the center of the SV40 origin of replication. This circular DNA was replicated in vitro by extracts from several types of human cells. The dimer was placed on the leading strand template of the first replication fork to encounter the(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)
Colony stimulating factor-1 (CSF-1) is a homodimeric glycoprotein that humorally regulates the proliferation and differentiation of mononuclear phagocytic cells and locally regulates cells of the female reproductive tract. Alternative splicing of the human CSF-1 mRNA leads to alternative expression of the CSF-1 homodimer as a secreted glycoprotein or as a(More)
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)
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)
