E1/E2/E3 Enzyme
E1 activating enzyme; E2 conjugating enzyme; E3 ligating enzyme; Ubiquitin activating enzyme; Ubiquitin conjugating enzyme; Ubiquitin ligase
Ubiquitin (UB) is a protein modifier that regulates many essential cellular processes. To initiate protein modification by UB, the E1 enzyme activates the C-terminal carboxylate of UB to launch its transfer through the E1-E2-E3 cascade onto target proteins. The E1 enzyme is the activating enzyme, to which ubiquitin is attached in an ATP-dependent reaction by a thioester bond. The E2 enzyme is the conjugating enzyme, to which the ubiquitin is transferred from the E1. The E3 is the ubiquitin ligase, which directly or indirectly catalyzes the transfer of the ubiquitin to the target protein (the substrate), with the formation of an isopeptide bond.

0 ImagesSkp2 inhibitor 3 is an orally active inhibitor of the Skp2-Cks1 complex, with an IC50 of 4.86 μM. Skp2 inhibitor 3 reduces Skp2 protein expression while upregulating the expression of p21 and p27. Skp2 inhibitor 3 inhibits colony formation and migration of cancer cells, and induces cell cycle arrest at the S phase. Skp2 inhibitor 3 suppresses tumor growth in xenograft mice. Skp2 inhibitor 3 can be used in the research of gastric cancer and prostate cancer.
-
Skp2 inhibitor 2
0 ImagesSkp2 inhibitor 2 is a Skp2-Cks1 protein-protein interaction inhibitor with a human IC50 of 0.57 μM. Skp2 inhibitor 2 binds to Skp2 at the interaction interface to block Skp2-Cks1 complex formation. Skp2 inhibitor 2 can be used for the research of gastric cancer, non-small cell lung cancer, breast cancer, prostate cancer.

U7D-1
0 ImagesU7D-1 is a USP7 PROTAC degrader that induces selective proteasomal degradation of USP7. U7D-1 destabilizes and downregulates the expression of variant PRC1 complex subunits PCGF1, RING1A and PCGF6, and also slightly reduces the protein level of KDM2B. U7D-1 decreases cell viability, arrests neuroblastoma cells at the G0/G1 cell cycle phase, and downregulates the expression of target genes of PAX3::FOXO1 in FP-RMS cells. U7D-1 increases the level of cleaved PARP in FP-RMS cells, induces cell apoptosis, and upregulates the expression of muscle differentiation markers MYH1 and MYF5. U7D-1 inhibits the growth and proliferation of p53 wild-type and mutant cancer cells, and regulates the apoptosis pathway and E2F pathway. U7D-1 is applicable to studies on neuroblastoma, fusion-positive rhabdomyosarcoma, p53-mutant cancers and cancer-related research.

MN551
0 ImagesMN551 is a covalent modulator of SOCS2 and CISH, with selectivity for SOCS2 and CISH over SOCS4. MN551 covalently modifies Cys111 in the SH2 domain of SOCS2 and Cys144 in the EF loop of the CISH SH2 domain, while only minimally modifying Cys471 in the BG loop of the SOCS6 SH2 domain. MN551 increases the thermal stability of the recombinant SOCS2-ElonginB-ElonginC complex and competitively blocks the binding of SOCS2 to its substrate; when delivered via the prodrug MN714, it blocks the intracellular recruitment of substrates by SOCS2. MN551 can serve as a chemical probe for investigating the biological functions of SOCS2 and its CRL5 complex, and also act as an E3 ligase-binding module in proteolysis-targeting chimeras (PROTACs).
