The disease is caused by mutations affecting the gene represented in this entry. Function CRBN_HUMAN Component of some DCX (DDB1-CUL4-X-box) E3 protein ligase complex, a complex that mediates the ubiquitination and subsequent proteasomal degradation of target proteins and is required for limb outgrowth and expression of the fibroblast growth factor FGF8. In the complex, may act as a substrate receptor. Regulates the assembly and neuronal surface expression of large-conductance calcium-activated potassium channels in brain regions involved in memory and learning via its interaction with KCNT1. Publication Abstract from PubMed Immunosuppressive Tregs, regulated by IKZF2 (Helios), promote tumor immune evasion and resistance to immune checkpoint therapies (ICTs). Targeting IKZF2 degradation offers a promising cancer immunotherapy approach. We developed a novel series of iso-indolinone-based glutarimides, identifying compound 55 as a potent, selective IKZF2 degrader with >90% D(max) in Jurkat cells, outperforming benchmarks DKY709 and PVTX-405. It exhibits strong selectivity over IMiD neo-substrates, favorable solubility, metabolic stability, and oral bioavailability in rodents. PK/PD studies confirmed profound, persistent IKZF2 degradation in mouse spleen and thymus after a single oral dose. As a promising early-stage tool, 55 provides a foundation for further preclinical evaluation in cancer immunotherapy.
