RAJQ14 is a BRD4 PROTAC-like CAP-TAC (Proteasome Cap Targeting Chimeras) degrader. RAJQ14 binds to 19S proteasome cap subunits RPN1, RPN10, RPN13, and USP14 to recruit target proteins to the proteasome for ubiquitination-independent, proteasome-dependent degradation. RAJQ14 can be used for the research of cancer (Pink: BRD4 Ligand (HY-181496); Blue: Proteasome Ligand (HY-128978); Black: Linker).

Description

RAJQ14 is a BRD4 PROTAC-like CAP-TAC (Proteasome Cap Targeting Chimeras) degrader. RAJQ14 binds to 19S proteasome cap subunits RPN1, RPN10, RPN13, and USP14 to recruit target proteins to the proteasome for ubiquitination-independent, proteasome-dependent degradation. RAJQ14 can be used for the research of cancer[1] (Pink: BRD4 Ligand (HY-181496); Blue: Proteasome Ligand (HY-128978); Black: Linker).

In Vitro

RAJQ14 (10 μM) selectively binds to the bromodomains of BRD2, BRD3, and BRD4, increasing their thermal stability[1].
RAJQ14 (10 μM; 2 h) binds to both RPN13 and BRD4 in live HEK293T cells[1].
RAJQ14 (0.1-2.5 μM; 2-24 h) induces dose-dependent and time-dependent degradation of BRD4 in HEK293T cells[1].
RAJQ14 (1 μM; 6 h) selectively induces degradation of BRD2, BRD3, and BRD4 in HEK293T cells, with no off-target degradation of other bromodomain-containing proteins[1].
RAJQ14 (0.1-2.5 μM; 24 h) induces BRD4 degradation in CRBN-knockout HEK293T cells that is independent of the E3 ligase CRBN[1].
RAJQ14 (1-100 μM; overnight) binds to multiple 19S proteasome cap subunits (including RPN1, RPN10, RPN13, and USP14) and BET proteins (BRD2, BRD3, BRD4) in HCT116 cells, independent of RPN13 expression[1].
RAJQ14 (0.1-2.5 μM; 24 h) induces BRD4 degradation in RPN13-knockou HCT116 cells independent of RPN13, likely via engagement of alternative 19S proteasome cap subunits[1].
RAJQ14 (0.1-2.5 μM; 24 h) induces BRD4 degradation in T47D-shRPN1-Dox cells that is not fully dependent on RPN1, as compensatory upregulation of RPN13 and RPN11 maintains degrader activity[1].
RAJQ14 (2.5 μM; 6 h) induces BRD4 degradation in HEK293T cells via a ubiquitination-independent mechanism, as BRD4 ubiquitination is not detected during degradation[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
