BackgroundGenes and proteins are organized into functional modular networks in which the network context of a gene or protein has implications for cellular function. Highly connected hub proteins, largely responsible for maintaining network connectivity, have been found to be much more likely to be essential for yeast survival.ResultsHere we invest...

BackgroundIn the yeast Saccharomyces cerevisiae, genes containing UASINO sequences are regulated by the Ino2/Ino4 and Opi1 transcription factors, and this regulation controls lipid biosynthesis. The expression level of INO2 and INO4 genes (INO-level) at different nutrient limited conditions might lead to various responses in yeast lipid metabolism....

In this study, the ku70 and ku80 homologs from the Aspergillus niger genome were identified and their function was analyzed using targeted mutagenesis. The role of the ku80 gene in non-homologous end-joining (NHEJ) was investigated by calculating the frequency of homologous recombination. The transformation test verified that the frequency of homol...

Oral-facial-digital syndrome type 1 (OFD1) is an X-linked dominant disease characterized by malformations of the face, oral cavity, and digits. Thus far, 18 small mutations in the OFD1 gene have been reported. Here, we describe, in one Japanese sporadic female OFD1 case, the presence of a novel pair of deletion mutations: a 4,094-bp deletion encomp...

BackgroundGroup II introns are mobile genetic elements that form conserved secondary and tertiary structures. In order to determine which of the conserved structural elements are required for mobility, a series of domain and sub-domain deletions were made in the Lactococcus lactis group II intron (Ll.LtrB) and tested for mobility in a genetic assay...
