QS-57
0 ImagesCat. No.: HY-169081QS-57 is a heterobifunctional targeted protein localization (TPL) agent. QS-57 binds to BRD4 via its JQ1 domain and covalently targets 14-3-3σ to form a ternary complex. QS-57 sequesters nuclear BRD4 in the cytoplasm, impairing the nuclear transcriptional regulatory function mediated by BRD4. QS-57 significantly reduces the nuclear BRD4 protein level and increases the cytoplasmic BRD4 protein abundance in cancer cells. QS-57 can be used for research on breast cancer and colorectal cancer.
