Recombinant human L3MBTL3 is a protein of interest in epigenetic regulation and cancer biology. L3MBTL3 belongs to the MBT (malignant brain tumor) domain-containing protein family, known for recognizing methylated histone marks and modulating chromatin compaction. It contains four MBT repeats that mediate interactions with mono- or dimethylated lysine residues on histones, particularly H4K20me1/2. linking it to transcriptional repression and heterochromatin maintenance.
The gene encoding L3MBTL3 resides on chromosome 6q23.2. a region frequently altered in cancers. Studies suggest dual roles: acting as a tumor suppressor by limiting oncogenic pathways through chromatin modification, while also being implicated in chemoresistance in certain malignancies. Recombinant versions are typically produced in E. coli or mammalian expression systems, enabling biochemical studies on its structure, histone-binding specificity, and interactions with polycomb repressive complexes.
Current research focuses on its crosstalk with DNA damage response pathways and potential as a therapeutic target. The recombinant protein serves as a tool for elucidating mechanisms of epigenetic silencing, designing chromatin-modifying drugs, and exploring its context-dependent roles in tumorigenesis. Its modular MBT domains also attract interest in synthetic biology for engineering chromatin-targeting molecules.
