UNC4976 (UNC-4976) is a potent cellular active positive allosteric modulator of CBX7, binds to CBX7 competitively with H3K27me3 peptides (IC50=20 nM), while increasing affinity for oligonucleotides.
UNC4976 (UNC-4976) is a potent cellular active positive allosteric modulator of CBX7, binds to CBX7 competitively with H3K27me3 peptides (IC50=20 nM), while increasing affinity for oligonucleotides.
UNC4976 displays >40-fold selectivity over CBX8 (IC50=890 nM).
The PAM activity of UNC4976 resulted in enhanced efficacy across three orthogonal cellular assays by simultaneously antagonizing H3K27me3-specific recruitment of CBX7 to target genes while increasing non-specific binding to DNA and RNA.
UNC4976 reequilibrates PRC1 away from H3K27me3 target regions.
