생화학적/생리학적 작용

RNA binding motif protein 39 (RBM39; CAPERα, HCC1) degradation-inducing SPLAM (SPLicing inhibitor sulfonAMide).
Tasisulam (LY573636) is a SPLAM (SPLicing inhibitor sulfonAMide) that bridges RNA binding motif protein 39 (RBM39; CAPERα, HCC1) and DCAF15 for interaction, thereby promoting (CUL4-DDB1-DDA1-DCAF15) E3 ubiquitin ligase complex-mediated RBM39 ubiquitination and subsequent proteasomal degradation. Tasisulam exerts selective toxicity in parental HCT116 cancer cultures (IC50 = 6.5 μM), but not those harboring non-CUL4-DCAF15-associating RBM39 G268V mutant even at a high concentration of 50 μM.

Indisulam is an aryl sulfonamide drug with selective anticancer activity. Its mechanism of action and the basis for its selectivity have so far been unknown. Here we show that indisulam promotes the recruitment of RBM39 (RNA binding motif protein 39)

The investigational drugs E7820, indisulam and tasisulam (aryl-sulfonamides) promote the degradation of the splicing factor RBM39 in a proteasome-dependent mechanism. While the activity critically depends on the cullin RING ligase substrate receptor DCAF15, the molecular details remain elusive. Here we

Indisulam and related sulfonamides recruit the splicing factor RBM39 to the CRL4-DCAF15 E3 ubiquitin ligase, resulting in RBM39 ubiquitination and degradation. Here, we used a combination of domain mapping and random mutagenesis to identify domains or residues that are necessary
