SMAD ubiquitylation regulatory factor 1 (Smurf1) was identified as a critical activator of the phosphoinositide 3-kinase (PI3K)–Akt pathway by promoting phosphoinositide-dependent protein kinase 1 (PDK1) neddylation and cytoplasmic complex of PDK1 assembled with Smurf1 and SETDB1 (cCOMPASS) assembly. Smurf1-antagonizing repressor of tumor 1 (SMART1), a highly selective degrader for Smurf1, was developed and suppressed the tumor growth of Kirsten rat sarcoma viral oncogene homolog (KRAS) mutant colorectal cancer.
