生物活性

YZ-836P is a Protein arginine methyltransferase 5 (PRMT5) targeting agent. YZ-836P promotes ubiquitination and proteasomal degradation of PRMT5 in a cereblon (CRBN)-dependent manner, which in turn reduces levels of its downstream target KLF5. YZ-836P induces G1 phase cell cycle arrest in triple-negative breast cancer cells. YZ-836P induces Apoptosis in triple-negative breast cancer cells. YZ-836P exerts cytotoxic effects on triple-negative breast cancer cells. YZ-836P inhibits the growth of triple-negative breast cancer patient-derived organoids. YZ-836P inhibits the growth of triple-negative breast cancer xenografts in nude mice. YZ-836P can be used for the research of triple-negative breast cancer[1]. (Pink: PRMT5 ligand (HY-173562); Blue: Cereblon ligand (HY-14658); Black: linker).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
