B-cell lymphoma/leukemia 11B is a protein that in humans is encoded by the BCL11B gene.[1][2][3]



This gene encodes a C2H2-type zinc finger protein and is closely related to BCL11A, a gene whose translocation may be associated with B-cell malignancies. The specific function of this gene has not yet been determined. Two alternatively spliced transcript variants, which encode distinct isoforms, have been reported.[3]

Recent research suggests that BCL11B is crucial for ameloblasts (the cells that produce tooth enamel) to form and work properly.[4]


BCL11B has been shown to interact with COUP-TFI.[5]
