Vesicle fusion is an indispensable cellular process required for eukaryotic cargo delivery. The Sec/Munc18 protein Munc18c is essential for insulin-regulated trafficking of glucose transporter4 (GLUT4) vesicles to the cell surface in muscle and adipose tissue. Previously, our biophysical and structural studies have used Munc18c expressed in SF9 insect cells. However to maximize efficiency, mini...

background: rotaviruses cause diarrhea in infants and young children worldwide. rotavirus outer capsid protein, vp7 is major neutralizing antigen that is important component of subunit vaccine to prevent rotavirus infection. many efforts have been done to produce recombinant vp7 that maintain native characteristics. we used baculovirus expression system to produce rotavirus vp7 protein and to s...

Baculovirus expression systems for recombinant proteins have found widespread use because they produce biologically active proteins more reliably than do bacterial or yeast expression systems, and the yields generally exceed those from mammalian expression systems. However, optimization of baculovirus yields remains an important issue, especially when biophysical studies are contemplated. Recen...

The H,K-ATPase responsible for gastric acidification is a heterodimeric (alpha and beta subunit) P-type ATPase, an integral protein of parietal cell apical membranes, which promotes the electroneutral exchange of K+ for protons, is stimulated by K+ and is inhibited by 2-methyl-8-(phenylmethoxy)imidazo[1, 2-alpha]pyridine-3-acetonitrile (SCH 28080). Hydropathy analysis of the catalytic alpha sub...

Influenza virus A (H1N1) is an important subtype of influenza virus that makes numerous consequences throughout the world. In the first step of viral attachment, main antigenic site of the HA1 domain from the globular head of hemagglutinin (HA) binds to human cell receptors, starting the disease process. In order to produce recombinant subunit protein vaccines, we focus on the nucleotide sequen...

Bluetongue virus (BTV) and epizootic hemorrhagic disease virus (EHDV) are orbiviruses that infect both livestock and wild ruminants. Antigenic cross-reactivity between BTV and EHDV often results in serologic misdiagnosis. Competitive enzyme-linked immunosorbent assays (c-ELISAs) show increased sensitivity and specificity for the identification of these viral diseases; however, the preparation o...
