SF  copurifies with PARP SB000062 and DNA-PK SB000055
SF  [9]; modified by DNA-PK [9]
FF  induces the formation of DNA loops [1]; binds to
FF  poly(dA-dT) and to poly(dA) poly(dT) tracks [1]; approx.
FF  300 isolated SAF-boxes are necessary to bind one molecule of
FF  the topoisomerase-M2 MAR SM0000048 [10]; binding shows
FF  cooperative effects [10]; approximately 20% of the total
FF  cellular hnRNP-U are crosslinked to chromosomal DNA in vivo
FF  [3] [6]; localizes to chromosomes in two-thirds of the
FF  mitotic cells [10]; binds to ds, ssDNA & RNA [3];
FF  forms complexes of high order with nucleic acids [6996,
FF  7010]; deletion of N-terminal 45 AA result in a decrease of
FF  proliferation [10]; assumed to function in the
FF  organization of chromosomal DNA & packaging of hnRNA in
FF  ribonucleoprotein particles [3]; cleaved during apotosis,
FF  but not during necrosis, to a non-DNA-binding protein
FF  [5]; small amounts proteolysed in apototic hematopoietic
FF  cells [8]; caution: heat stabilization during matrix
FF  preparation lead to changes in distribution [7];
FF  concluded to contribute to S/MAR-binding activity of p114
FF  SB000030 [9]; interacts with p300 SB000083 [12];
FF  no binding to S/MARs in cells transfromed with adenovirus or
FF  SV40 [12]; no binding of p300-SAF-A to S/MAR elements of
FF  expressed gene [12]
