Genes Involved and Proteins

Gene name
BCL6 (B-Cell Lymphoma 6)
Protein description
706 amino acids; composed of a NH2-term BTB/POZ domain (amino acids 1-130 (32-99 according to Swiss-Prot)) which mediates homodimerization and protein-protein interactions with other corepressors (including HDAC1 and NCOR2/SMRT) to constitute a large repressing complex, another transcription repression domain (191-386), PEST sequences (300-417) with a KKYK motif (375-379), and six zinc finger at the C-term (518-541, 546-568, 574-596, 602-624, 630-652, 658-681), responsible for sequence specific DNA binding. Transcription repressor; recognizes the consensus sequence: TTCCT(A/C)GAA (Albagli-Curiel, 2003).
Gene name
SRSF3 (serine/arginine-rich splicing factor 3)
Protein description
164 amino acids (alternate splicing 124 aa); SFRS3 is a member of the serine- and arginine-rich (SR) protein family; comprise a RNA recognition motifs (RRM) (amino acids 10-83) and an SR domain (aa 86-164) according to Swiss-Prot; role in splicing of mRNA precursors; promote the export of some cellular mRNAs; possible role in cell cycle.

t(3;6)(q27;p21) has been described in a few cases where SFRS3/BCL6 rearrangement has not been ascertained, or where another hybrid gene has been uncovered.
