Cryo-EM structure of the murine DNMT3A-TCL1A complex
Understanding how a protein blocks cancer-driving mutations could lead to new treatments targeting the faulty control of genes in blood cancers.
Cryo-EM reveals DNMT3A-TCL1A heterohexamer (two TCL1A dimers bound to DNMT3A catalytic domain) with TCL1A producing allosteric inhibition of DNMT3A at the DNMT3L interface—defining the structural mechanism for TCL1A-driven epigenetic dysregulation in CLL and AML. This record was retained from the prior triage attempt for PubMed pipeline handoff.

Why it surfaced
First cryo-EM structure of the DNMT3A-TCL1A oncogenic complex; provides structural basis for drug design targeting TCL1A-driven epigenetic disruption in CLL and T-cell leukemia; murine system limits direct clinical translation confidence but mechanism is conserved.
