Birt-Hogg-Dubé syndrome, a hamartoma disorder characterized by benign tumors of the hair follicle, lung cysts, and renal neoplasia, is caused by germ-line mutations in the BHD(FLCN) gene, which encodes a tumor-suppressor protein, folliculin (FLCN), with unknown function. The tumor-suppressor proteins encoded by genes responsible for several other hamartoma(More)
The advent of systems biology necessitates the cloning of nearly entire sets of protein-encoding open reading frames (ORFs), or ORFeomes, to allow functional studies of the corresponding proteomes. Here, we describe the generation of a first version of the human ORFeome using a newly improved Gateway recombinational cloning approach. Using the Mammalian(More)
Griffithsin (GRFT) is a novel anti-HIV protein isolated from the red alga Griffithia sp. The potent anti-viral activity of GRFT against both laboratory and primary isolates of HIV at picomolar concentrations makes this protein an attractive candidate microbicide to prevent sexual transmission of HIV. Here, we describe the recombinant production and(More)
An efficient cell-free protein synthesis system has been developed using a novel energy-regenerating source. Using the new energy source, 3-phosphoglycerate (3-PGA), protein synthesis continues beyond 2 h. In contrast, the reaction rate slowed down considerably within 30-45 min using a conventional energy source, phosphoenol pyruvate (PEP) under identical(More)
To verify the genome annotation and to create a resource to functionally characterize the proteome, we attempted to Gateway-clone all predicted protein-encoding open reading frames (ORFs), or the 'ORFeome,' of Caenorhabditis elegans. We successfully cloned approximately 12,000 ORFs (ORFeome 1.1), of which roughly 4,000 correspond to genes that are untouched(More)
BACKGROUND Virus-like particles (VLPs) of Ebola virus (EBOV) and Marburg virus (MARV) produced in human 293T embryonic kidney cells have been shown to be effective vaccines against filoviral infection. In this study, we explored alternative strategies for production of filovirus-like particle-based vaccines, to accelerate the development process. The goal(More)
In parallel with the production of genomic sequence data, attention is being focused on the generation of comprehensive cDNA-sequence resources. Such efforts are increasingly emphasizing the production of high-accuracy sequence corresponding to the entire insert of cDNA clones, especially those presumed to reflect the full-length mRNA. The complete(More)
Secretion of recombinant proteins is a common strategy for heterologous protein expression using the yeast Kluyveromyces lactis. However, a common problem is degradation of a target recombinant protein by secretory pathway aspartyl proteases. In this study, we identified five putative pfam00026 aspartyl proteases encoded by the K. lactis genome. A set of(More)
The ability to clone and manipulate DNA segments is central to molecular methods that enable expression, screening, and functional characterization of genes, proteins, and regulatory elements. We previously described the development of a novel technology that utilizes in vitro site-specific recombination to provide a robust and flexible platform for(More)
