简介内容:ALV1 is a potent degradation agent of Ikaros and Helios, with similar degradation activity against IKZF1/2/3. ALV1 significantly reduced the protein abundance of IKZF1-4, CK1α (casein kinase 1α, CSNK1A1) and ribosomal protein RPL4, and induced Helios/CRBN dimerization, which promoted IL-2 secretion.
