B-cell lymphoma 3-encoded protein is a protein that in humans is encoded by the BCL3 gene.[1][2]

This gene is a proto-oncogene candidate. It is identified by its translocation into the immunoglobulin alpha-locus in some cases of B-cell leukemia. The protein encoded by this gene contains seven ankyrin repeats, which are most closely related to those found in I kappa B proteins. This protein functions as a transcriptional coactivator that activates through its association with NF-kappa B homodimers. The expression of this gene can be induced by NF-kappa B, which forms a part of the autoregulatory loop that controls the nuclear residence of p50 NF-kappa B.[3]

Like BCL2, BCL5, BCL6, BCL7A, BCL9, and BCL10, it has clinical significance in lymphoma.
