TCIP3 is a bivalent molecular glue (molecular glue) that can simultaneously bind to both p300/CBP and BCL6. It redirects p300 and CBP to activate programmed cell death genes, which are typically repressed by the oncogenic driver BCL6. TCIP3 is useful for studying diffuse large B-cell lymphoma (DLBCL) and is not toxic to untransformed tonsil lymphocytes or fibroblasts.
