SF   the low-affinity elements with 1000-fold lower affinity [14];
SF   within the IgH enhancer, both elements adjacent to each other cooperatively bind two Oct-2 molecules [14];
SF   even higher affinity of one Oct-2 molecule for the composite motif ATGCTAATGARAT [32];
SF   however, Oct-2 does not interact with viral VP16 unless Ala-317 is replaced by Glu as in Oct-1 [36] [37];
SF   DNA-binding specificity indistinguishable from that of Oct-1 [3];
SF   POUs induces bending of the bound octamer DNA [11];
SF   whole POU domain interacts with the C-terminal core domain of TBP [38];
SF   2 synergizing trans-activating domains [39] [41] [6] [8];
SF   the first two modularly acting Gln-clusters within the N-terminal activation domain are particularly important [46] [8];
SF   for full effect, C-terminal extensions of this domain are required [6] [8];
SF   it possibly depends on additional factors [39] [41];
SF   and it is reported to activate exclusively from proximal binding sites, whereas activation from distantly located binding sites requires the C-terminal activation domain II [35];
SF   activation domain II depends on an additional B-cell specific activity [41] [43];
SF   B-cell specific activity as Bob1/OBF-I [40] [47] [48];
