A conserved quadruplex motif located in a transcription activation site of the human c-kit oncogene.


The c-kit gene encodes a receptor tyrosine kinase, whose engagement by its ligand triggers signals leading to cell proliferation. c-kit activity is elevated in gastrointestinal stromal tumors (GISTs), and its therapeutic inhibition by small molecules such as imatinib is clinically validated. We identified a putative quadruplex forming 21-nucleotide sequence… (More)
