protein substrate competitive inhibitor, SAM uncompetitive inhibitor of PRMT5



Protein target names: PRMT5

Mechanism of action: protein substrate competitive inhibitor, SAM uncompetitive inhibitor

In Vitro Validations

Uniprot ID: O14744
Target Class: Epigenetics
Target SubClass: Protein methyltransferase
Potency: IC50
Potency Value: 4 nM
Potency Assay: Homogeneous time-resolved fluorescence (HTRF) assay under balanced conditions to monitor the monomethylation of H4R3 on a histone H4 peptide by PRMT5:MEP50.
PDB ID for probe-target interaction (3D structure): --
Structure-activity relationship: Yes. Early SAR exploration around the THIQ motif confirmed the contribution of the cation−π interaction with cofactor SAM and was thus retained within the series as a key binding interaction.
Target aliases:
Protein arginine N-methyltransferase 5, SKB1, JBP1 ...
