XX SF Q-rich activation domain may mediate self-aggregation [7]; SF S/T-rich stretch [6]; SF base contacts arise from the second and the third zinc fingers [10]; SF Zn2+ can be substituted for Cd2+, Co2+, less favourable: Mn2+, Ni2+; SF thionein inhibits DNA-binding; SF Kd 0.41-0.53 nM; SF t1/2 for binding to and dissociation from DNA < 1 min; SF phosphorylation (DNA-dependent protein kinase); SF homology to factors SP3 and SP4 [12]; SF possibly glycosylated [8]; SF interacts with NF-kappaB by its trans-acting domain when bound to an SF adjacent site [6]; SF interacts secies-specifically with human, but not with Drosophila TFIID SF complex [2]; XX CP (HeLa); ubiquitous [14] XX FF multimerization leads to superactivation; FF effect of Sp1-sites depends on distance to TATA-box [22]; FF synergistically cooperates with E2 at BPV promoters [17]; FF highly specific cooperation with NF-kappaB [6]; FF binding inhibited by formation of triple-stranded structures [13]; FF binds to its site even when reconstituted into nucleosome cores [7]; FF affinity for nucleosomal DNA is reduced relative to naked DNA [7]; XX IN T00205; E2; BPV-1, bovine papilloma virus type 1.
