Interplay of three G‑quadruplex units in the KIT promoter
2019
The proto-oncogene KIT encodes for a tyrosine kinase receptor, which is a clinically validated target for treating gastrointestinal stromal tumors. The KIT promoter contains a G-rich domain within a relatively long sequence potentially able to form three adjacent G-quadruplex (G4) units, namely, K2, SP, and K1. These G4 domains have been studied mainly as single quadruplex units derived from short truncated sequences and are currently considered promising targets for anticancer drugs, alternatively to the encoded protein. Nevertheless, the information reported so far does not contemplate the interplay between those neighboring G4s in the context of the whole promoter, possibly thwarting dru…
