EB-TCIP (BAK-04-212) is a bivalent molecule comprised of AP1867 and BI-3812 (HY-111381). EB-TCIP can form a reversible ternary complex between FKBPF36V and BCL6BTB. EB-TCIP recruits FKBP12F36V-tagged EWS/FLI1 to DNA sites bound by the transcriptional regulator BCL6, leading to rapid expression of BCL6 target genes (eg: SOCS2 and CXCL11). EWS/FLI1 is a fusion transcription factors in Ewing sarcoma. EB-TCIP can be used for research of deregulated transcription in cancer[1].
