The M2 protein of influenza A virus is expressed on the surfaces of infected cells, and a monoclonal antibody to this protein inhibits plaque enlargement of sensitive influenza A viruses without reducing plaque titer (S.L. Zebedee and R.A. Lamb, J. Virol. 62:2762-2772, 1988). In the current study, passively transferred monoclonal antibody to M2 reduced the level of replication of influenza A vi...
Respiratory syncytial virus (RSV) RNA synthesis occurs in cytoplasmic inclusion bodies (IBs) in which all the components of the viral RNA polymerase are concentrated. In this work, we show that RSV P protein recruits the essential RSV transcription factor M2-1 to IBs independently of the phosphorylation state of M2-1. We also show that M2-1 dephosphorylation is achieved by a complex formed betw...
RNA synthesis by the paramyxovirus respiratory syncytial virus, a ubiquitous human pathogen, was found to be more complex than previously appreciated for the nonsegmented negative-strand RNA viruses. Intracellular RNA replication of a plasmid-encoded "minigenome" analog of viral genomic RNA was directed by coexpression of the N, P, and L proteins. But, under these conditions, the greater part o...
Reconstitutively active G protein-coupled receptors purified from baculovirus-infected insect cells.
The turkey beta-adrenergic receptor (beta-AR), the m1 and m2 forms of the human muscarinic cholingeric receptor (MAChR) and several other mutant and wild-type G protein-coupled receptors were produced in insect Sf9 cells by infection with recombinant baculoviruses. Maximal expression for most receptors was 5-30 pmol receptor/mg protein (2-15 nmol/liter culture). The receptors displayed typical ...
The mRNA encoding the M2 protein of respiratory syncytial (RS) virus contains two open reading frames (ORFs). ORF1 encodes the 22-kDa structural protein, M2, and ORF2 has the potential to encode a 10-kDa protein (90 amino acids). Using a vaccinia virus T7 expression system, we examined the RNA synthetic activities of mono- and dicistronic subgenomic replicons of RS virus by direct metabolic lab...
Diapause hormone (DH) and PBAN (pheromone biosynthesis-activating neuropeptide) are two important insect neuropeptides regulating development and reproduction respectively. In the present study, we report two Bombyx mori transcription factors interacting specifically with the promoter of Bom-DH-PBAN (where Bom-DH stands for B. mori DH); we named them DHMBP-1 and -2 (DH-modulator-binding protein...
We have previously reported that a heat-stable activator for ganglioside metabolism, G(M2) activator, potently stimulates ADP-ribosylation factor (ARF)-dependent phospholipase D (PLD) activity (presumably PLD1) in an in vitro system [Nakamura, Akisue, Jinnai, Hitomi, Sarkar, Miwa, Okada, Yoshida, Kuroda, Kikkawa and Nishizuka (1998) Proc. Natl. Acad. Sci. U.S.A. 95, 12249-12253]. However, littl...
Molecular weight markers that can tolerate denaturing conditions and be auto-detected by secondary antibodies offer great efficacy and convenience for Western Blotting. Here, we describe M&R LE protein markers which contain linear epitopes derived from the heavy chain constant regions of mouse and rabbit immunoglobulin G (IgG Fc LE). These markers can be directly recognized and stained by a wid...
