MrTAC-8
MrTAC-8, methylarginine-targeting chimera (MrTAC), is a BRD4 degrader with DC50 values of 46 nM in HeLa cells. MrTAC-8 recruits PRMT1, PRMT3, PRMT4, PRMT5, and PRMT7 to target proteins, inducing arginine methylation that triggers lysosomal degradation. MrTAC-8 degrades proteins across diverse subcellular localizations and independent of native proteolytic routes. MrTAC-8 can be used for the research of cervical cancer, glioblastoma.

BRD4 |
MrTAC-8 (0.01 nM-10 μM; 24 h) potently induces lysosomal degradation of endogenous BRD4 via catalytically active PRMT5 recruitment, with DC50 values of 46 nM in HeLa cells, 67 nM in U87 cells, and 4.8 μM in HEK293 cells[1].
MrTAC-8 (1 μM; 2 h) blocks BRD4 degradation in HeLa cells when pre-treated with lysosomal inhibitors bafilomycin and Chloroquine (HY-17589A), restoring BRD4 levels to 110% of DMSO control[1].

Result:Blocked BRD4 degradation when pre-treated with lysosomal inhibitors bafilomycin and Chloroquine, restoring BRD4 levels to 110% of DMSO control.
Reduced BRD4 levels to 100% of DMSO control in cells expressing catalytically dead (E444Q) PRMT5 at 1 μM, compared to 15% reduction in cells expressing wild-type PRMT5.
Enriched BRD4 in SDMA-positive fractions after treatment, confirming proximity-induced arginine methylation.
