Only the more recent case (Akasaka et al., 2003) was studied for gene rearrangements.

BCL6 (B-Cell Lymphoma 6)

3q27.3

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). Role in germinal centers of lymphoid follicles. BCL6 prevents ATM and TP53 to induce apoptosis in response to DNA rearrangements such as somatic hypermutation and class switch recombination. Therefore essential for normal B cell development.

NAPA (N-ethylmaleimide-sensitive factor attachment protein, alpha)

19q13.32

295 amino acids; SNARE protein found in the endoplasmic reticulum and implicated in protein trafficking, which possesses anti-apoptotic properties by promoting resistance to cisplatin in cancer cells by inducing the degradation of TP53 (Wu et al., 2011).
