SETDB1-TTD-IN-1 |
SETDB1‑TTD‑IN‑1 is a SETDB1 methyltransferase activator and a competitive inhibitor of the SETDB1 tandem tudor domain (SETDB1‑TTD), binding SETDB1‑TTD with a Kd of 88 nM and showing strong selectivity over other tudor and bromodomain proteins. It enhances SETDB1 catalytic activity, promoting Akt1 Lys64 methylation and subsequent Akt1 Thr308 phosphorylation and activation. By blocking SETDB1‑TTD binding to histone H3 peptides, it drives global gene‑expression changes and functions as a tool compound to study SETDB1‑TTD, including in breast cancer models. |
