Adenovirus (Ad) fiber proteins are responsible for the initial attachment of the virion to the cell membrane. Most Ad vectors currently in use are based on the Ad type 5 (Ad5), which belong to subgroup C, and use the coxsackievirus and adenovirus receptors (CAR) as the initial receptor. Ad35, which belongs to subgroup B, recognizes unknown receptor(s) other than CAR. In this study, the feasibility...
Differential display-polymerase chain reaction was used to compare gene expression between human chondrosarcoma cell lines and normal cartilage. A new gene, CSAGE, has been cloned and belongs to a gene family that includes the taxol resistance associated gene (TRAG)-3. CSAGE, like TRAG-3, does not confer resistance to taxol when transfected in vitro. Both genes have alternatively spliced variants...
The current model of short interspersed nuclear element (SINE) mobility suggests that these non-coding retroposons are able to recruit for their own benefits the enzymatic machinery encoded by autonomous long interspersed nuclear elements (LINEs). The recent characterization of potential SINE-LINE partner pairs that share common 3′ end sequences concurs with this model and has led to a potent picture...
ERp29 is a soluble protein localized in the endoplasmic reticulum (ER) of eukaryotic cells, which is conserved in all mammalian species. The N-terminal domain of ERp29 displays sequence and structural similarity to the protein disulfide isomerase despite the lack of the characteristic double cysteine motif. Although the exact function of ERp29 is not yet known, it was hypothesized that it may facilitate...
The E2 enzyme, Ubc13, and the E2 enzyme variants, Uevs, form stable, high affinity complexes for the assembly of Lys63-linked ubiquitin chains. This process is involved in error-free DNA postreplication repair, the activation of kinases in the NF-κB signaling pathway and possibly other cellular processes. To further investigate the roles played by Ubc13 in a whole animal model, we report here the...
The fruiting body of Polysphondylium pallidum is composed of whorls of branches along the axis of a primary stalk. In the course of fruiting body formation, the interval between neighboring whorls and the number and the spacing of branches in a whorl are highly regulated. In this study, using restriction enzyme mediated integration mutagenesis, we have obtained a mutant (strain M6226) with thicker...
Sint1 (sept9), a murine gene of the septin family, was previously isolated as a putative proto-oncogene involved in T-cell lymphomagenesis. We now present its genomic structure and report on nine exons shared by all identified variants and at least four alternatively spliced 5′ exons. Northern blot analyses using a Sint1 cDNA probe showed in almost all examined tissues two predominant transcripts...
We performed cDNA and genomic cloning, sequencing and promoter analysis of the putative human O-sialoglycoprotein endopeptidase gene OSGEP (a homologue of gcp, a Pasteurella haemolytica A1 glycoprotease). The cloned OSGEP cDNA is 1311 nucleotides long, and encodes a protein consisting of 335 amino acids with predicted molecular mass of 36.4 kDa. The amino acid sequence of OSGEP showed 29.7% identity...
Parkinson‘s disease (PD) is a common neurodegenerative disorder with clinical features of bradykinesia, rigidity and resting tremor resulting from the deficiency of dopamine in the nigrostriatal system. Previously we mapped a susceptibility gene for an autosomal dominant form of PD to a 10.6 cM region of chromosome 2p (PARK3; OMIM 602404). Here we report the identification and characterization of...
The Drosophila eyes absent (eya) gene has a role in regulating cell death and/or differentiation and is expressed throughout development. We evaluated the transcripts and proteins encoded by one of the human homologues of Drosophila eya coined Eyes Absent 2 (EYA2). Interestingly, EYA2 was expressed in several neuroblastoma cell lines as four distinct transcripts having alternative 5′-ends, whereas...
Lesions in the anhidrotic ectodermal dysplasia (EDA) gene cause the recessive human genetic disorder X-linked anhidrotic ectodermal dysplasia, which is characterized by the poor development of ectoderm-derived structures. Ectodysplasin-A, the protein encoded by the EDA gene, is a member of the tumor necrosis factor ligand superfamily that forms a collagen triple helix, suggesting functions in signal...
A genomic DNA region of over 80 kb that contains the complete biosynthetic gene cluster for the synthesis of the antifungal polyketide metabolite soraphen A was cloned from Sorangium cellulosum So ce26. The nucleotide sequence of the soraphen A gene region, including 67,523 bp was determined. Examination of this sequence led to the identification of two adjacent type I polyketide synthase (PKS) genes...
