This gene encodes a C2H2 type zinc-finger protein by its similarity to the mouse Bcl11a/Evi9 protein. The corresponding mouse gene is a common site of retroviral integration in myeloid leukemia, and may function as a leukemia disease gene, in part, through its interaction with BCL6. During hematopoietic cell differentiation, this gene is down-regulated. It is possibly involved in lymphoma pathogenesis since translocations associated with B-cell malignancies also deregulates its expression. Multiple transcript variants encoding several different isoforms have been found for this gene.Synonyms: B-cell CLL/lymphoma 11A, B-cell lymphoma/leukemia 11A, BCL11A, COUP-TF-interacting protein 1, CTIP1, EVI9, Ecotropic viral integration site 9 protein homolog, KIAA1809
