BCL11B (B-cell lymphoma/leukemia 11B) is a zinc finger transcription factor that plays critical roles in immune regulation, neurodevelopment, and cellular differentiation. It belongs to the BCL11 gene family, which includes BCL11A and BCL11B, both involved in transcriptional repression through interactions with chromatin-modifying complexes like the NuRD complex. BCL11B is predominantly expressed in the nervous system, T lymphocytes, and epithelial tissues, where it regulates gene expression networks essential for cell fate determination and function.
In the immune system, BCL11B is indispensable for T-cell development, particularly during the transition from double-negative to double-positive thymocytes. It suppresses alternative lineage programs (e.g., NK or dendritic cells) while promoting T-cell receptor (TCR) rearrangement and maturation. In the brain, it influences cortical neuron migration and dendritic morphogenesis, with disruptions linked to neurodevelopmental disorders. Additionally, BCL11B has tumor-suppressive or oncogenic roles depending on cellular context, implicated in T-cell malignancies, gliomas, and epithelial cancers.
Recombinant BCL11B protein is engineered to study its molecular interactions, DNA-binding properties, and regulatory mechanisms. Produced via prokaryotic or eukaryotic expression systems, it often includes affinity tags (e.g., His-tag) for purification. Researchers use it to investigate its role in gene silencing, chromatin remodeling, and signaling pathways (e.g., Wnt/β-catenin). Its applications extend to disease modeling, drug screening (e.g., targeting BCL11B-dependent cancers), and exploring therapeutic strategies, such as modulating its expression in CAR-T cell engineering. Despite progress, the dual roles of BCL11B in different tissues and its context-dependent post-translational modifications remain active areas of study.
