背景信息

PRDM11 (PR/SET Domain 11) is a member of the PRDM family of transcriptional regulators characterized by a conserved PR/SET homology domain, which shares structural similarity with histone methyltransferases (HMTs). While many PRDM proteins exhibit HMT activity, PRDM11 lacks intrinsic enzymatic function due to substitutions in critical catalytic residues. Instead, it likely acts as an epigenetic adaptor by recruiting chromatin-modifying complexes. Structurally, PRDM11 contains an N-terminal PR domain followed by multiple zinc finger motifs, enabling DNA binding and protein interactions.

Functionally, PRDM11 is implicated in DNA damage response and genomic stability. Studies link it to the resolution of DNA replication stress by facilitating homology-directed repair (HDR). In B-cell development, PRDM11 collaborates with transcription factors like PAX5 to regulate gene networks critical for differentiation. Aberrant PRDM11 expression or mutations are associated with lymphoid malignancies, particularly diffuse large B-cell lymphomas (DLBCLs), where it may act as a tumor suppressor.

Evolutionarily conserved across vertebrates, PRDM11 shows tissue-specific expression patterns, predominantly in immune and germline cells. Its regulatory mechanisms remain partially understood but may involve post-translational modifications and interactions with pathways like NF-κB. Ongoing research aims to clarify its roles in cancer biology and potential therapeutic targeting.
