The regulatory G4 motif of the Kirsten ras (KRAS) gene is sensitive to guanine oxidation: implications on transcription.

abstract：:RBD-1 is the Caenorhabditis elegans homolog of Mrd1p, which was recently shown to be required for 18S ribosomal RNA (rRNA) processing in yeast. To gain insights into the relationship between ribosome biogenesis and the development of multicellular organisms, we examined the expression and function of RBD-1. Maternal R...
