Numerous regulatory genes have G-rich regions that can potentially form quadruplex structures, possibly playing a role in transcription regulation. We studied a G-rich sequence in the BCL2 gene 176-bp upstream of the P1 promoter for G-quadruplex formation. Using circular dichroism (CD), thermal denaturation and dimethyl sulfate (DMS) footprinting, we found that a single-stranded oligonucleotide...
The hepatitis A virus cellular receptor 1 (HAVcr-1) cDNA codes for a class I integral membrane glycoprotein, termed havcr-1, of unknown natural function which serves as an African green monkey kidney (AGMK) cell receptor for HAV. The extracellular domain of havcr-1 has an N-terminal Cys-rich region that displays homology with sequences of members of the immunoglobulin superfamily, followed by a...
Mitochondrial DNA (mtDNA) is packed into highly organized structures called mitochondrial nucleoids (mt-nucleoids). To understand the organization of mtDNA and the overall regulation of its genetic activity within the mt-nucleoids, we identified and characterized a novel mtDNA packaging protein, termed Glom (a protein inducing agglomeration of mitochondrial chromosome), from highly condensed mt...
