Description 5 exons, with a CpG island in 5' of the gene
Transcription the major transcript is the longest transcript: (5941 bp); other transcripts of 3.8 kb and 1.5 kb; alternate splices in exon 4


Description 835 amino acids, predicted molecular weight of 91.3 kDa for the longest isoform, called BCL11AXL, with 6 Kruppel C2H2 zinc fingers, a prolin rich domain, and an acidic domain; 773 and 243 amino acids for the BCL11AL and the BCL11AS respectively
Expression expressed in the fetal brain; low level or undetectable expression in most adult tissues, apart from lymph nodes, thymus, and bone marrow.
Function contains DNA binding motifs (Zn fingers)
Homology Evi9 (mouse); human BCL11B (14q32.1)

Implicated in

Entity in B-cell malignancies
Disease chronic lymphocytic leukemia / immunocytoma aggressive disease; possibly also other t(2;14)(p13;q32) in other B-ell diseases (acute lymphocytic leukemia, myeloma, ...) involve the same genes, but probably not Hodgkin disease cases with 2p amplification
Cytogenetics most often the sole anomaly
Hybrid/Mutated Gene head to head translocation of BCL11A with IGH switch sequences on the der(2)
Oncogenesis BCL11A is overexpressed
