Anatomy and functions of PBF

Domaina Disordered or ordered structureb Probable phosphorylation sitesc Probable binding sites to cellular factorsd Function
I (1–125) Disordered region (1–72) Ordered region (86–128) 7 sites 1 site (1–22) Unknown
II (126–215) Disordered region (131–216) 8 sites 2 sites (166–182; 193–206) Unknown
III (216–301) Ordered region (279–302) 11 sites 1 site (277–304) -Monopartite NLS (PAPRKRKNSVK, 267–277)e
-Zinc finger domain (279–302)
-Rich G-C DNA binding site of HPV type 8 [1]
IV (302–483) Disordered region (304–513) 18 sites 3 sites (320–341; 359–372; 393–416) -Binding to 14-3-3β (393–398; 444453). PBF must be phosphorylated at Ser 447, 449 and 451 [5].
-Sequence recognized by cytotoxic T cells in the context HLA-A24 [2].

Parentheses indicate the amino acid residues position. Bold residues indicate the high affinity site. Identified in this paper using: aMammoth analysis; bIntfold, disEMBL and Metadisorder analyses; cNetPhos 2.0; dANCHOR; ecNLS Mapper, NucPred, and PSORT II analyses.
