SF   no homodimerization, but heterodimerization with JunD or JunB;
SF   binds to AP-1 sites, most likely as a heterodimer with JunD or JunB [11] [13] [14];
SF   splice variant: FosB T00291 [1] [2] [3] [5] [8];
SF   deltaFosB lacks a portion of the C-terminal transactivation domain present in FosB;
SF   mRNA for deltaFosB produces three variants of proteins, 37, 35 and 33 kDa, as a result of the alternative AUG codons [14];
SF   the 37 and 35 kDa deltaFosB proteins are extremely stable, they are detectable several days after induction [14];
XX
CP   brain, especially striatum (region important for addiction) [10] [12].
XX
FF   activator, either similar to FosB or weaker [1] [8];
FF   does not repress c-fos expression [1];
FF   blunts c-Fos and FosB activities and reduces transformation by v-Fos, c-Fos, or FosB [2] [3] [8] [9];
FF   does not reduce cell proliferation [1];
FF   it is able to transform, e. g., Rat-1A cells consistent with the role of N-terminal sequences in transformation [4] [5];
FF   plays an important role in behavioral responses to cocaine [10];
FF   may mediate long-lasting changes in gene expression that increase sensitivity to cocaine and thus contribute to brain addiction [11] [12];
FF   induces expression of glutamate receptor subunit GluR2 [11];
FF   might decrease expression of dynorphin [12];
FF   induces expression of the cdk5 gene [13] [15];
