Abstract:Purine-rich element binding protein
B (Purβ) is a single-stranded
DNA (ssDNA) and RNA-binding protein that functions as a transcriptional
repressor of genes encoding certain muscle-restricted contractile
proteins in the setting of cellular stress or tissue injury. A prior
report from our laboratory implicated specific basic amino acid residues
in the physical and functional interaction of Purβ with the
smooth muscle-α actin gene (Acta2) promoter.
