We report two serotonin (5-hydroxytryptamine, 5-HT) receptors, MR22 and REC17, that belong to the G-protein-associated receptor superfamily. MR22 and REC17 are 371 and 357 amino acids long, respectively, as deduced from nucleotide sequence and share 68% mutual amino acid identity and 30-35% identity with known catecholamine and 5-HT receptors.

A mutant form of SecY, SecY-d1, was previously suggested to sequester a component(s) of the protein translocator complex. Its synthesis from a plasmid leads to interference with protein export in Escherichia coli. SecE is a target of this sequestration, and its overproduction cancels the export interference. We now report that overexpression of another(More)
NF-kappa B is a potent inducible transcription factor that regulates many genes in activated T cells. In this report we examined the ability of different subunits of NF-kappa B to enhance HIV-1 transcription in vitro with chromatin templates. We find that the p65 subunit of NF-kappa B is a strong transcriptional activator of nucleosome-assembled HIV-1 DNA,(More)
Lymphoid enhancer-binding factor 1 (LEF-1) is a regulatory high mobility group (HMG) protein that activates the T cell receptor alpha (TCR alpha) enhancer in a context-restricted manner in T cells. In this paper we demonstrate that the distal region of the human immunodeficiency virus-1 (HIV-1) enhancer, which contains DNA-binding sites for LEF-1 and Ets-1,(More)
Replication of Moloney murine leukemia virus requires a readthrough translation mechanism to generate the Gag-Pol polyprotein. One of the final products of this polyprotein is the protease (PR), which is required to generate the mature virion proteins. The assembly of Gag and Gag-Pol polyprotein into a virion followed by activation of the viral protease is(More)
This document was prepared by the Safety Pharmacology Subcommittee of the Oligonucleotide Safety Working Group (OSWG), a group of industry and regulatory scientists involved in the development and regulation of therapeutic oligonucleotides. The mission of the Subcommittee was to develop scientific recommendations for the industry regarding the appropriate(More)
We have previously shown that a molecule consisting of a fusion of a Ca(2+)-dependent nuclease (from Staphylococcus aureus) to a retroviral coat protein specifies a potent antiviral specific for that retrovirus. Genes specifying such fusion proteins can be delivered to virus-susceptible cells, providing an antiviral gene therapy aimed at limiting virus(More)
Methyl- and phenyl-substituted N-(ethoxycarbonyl)-2-azabicyclo[2.2.0]hex-5-enes 6 were reacted with NBS in wet DMSO to afford bromohydrins. Mixtures of unrearranged 6-exo-bromo-5-endo-hydroxy-2-azabicyclo[2.2.0]hexanes 7a,b and rearranged 5-anti-bromo-6-anti-hydroxy-2-azabicyclo[2.1.1]hexanes 8a,b were formed stereoselectively from the parent alkene 6a and(More)
Recently, remarkable progress has been made in developing effective combination drug therapies that can control but not cure retroviral replication. Even when effective, these drug regimens are toxic, they require demanding administration schedules, and resistant viruses can emerge. Thus the need for new gene-based therapies continues. In one such approach,(More)
