[https://www.uniprot.org/uniprot/WHY1_SOLTU WHY1_SOLTU] Single-stranded DNA-binding protein that acts as a transcriptional activator of the pathogenesis-related gene PR-10a. Upon elicitation, binds a 30bp promoter sequence known as elicitor element response (ERE) and is required for PR-10a expression.<ref>PMID:10948264</ref> <ref>PMID:12080340</ref> <ref>PMID:14960277</ref>

The crystal structure of p24, the single-stranded DNA (ssDNA) binding subunit of the plant defense transcription factor PBF-2, has been determined to 2.3 A resolution. p24 is representative of a novel family of ubiquitous plant-specific proteins that we refer to as the Whirly family because of their quaternary structure. PBF-2 is composed of four p24 molecules that interact through a helix-loop-helix motif. This interaction produces a central pore, with beta-strands radiating outwards, resulting in a whirligig appearance to the quaternary structure. The noncrystallographic C(4) symmetry arrangement of p24 subunits is novel for ssDNA binding proteins and may explain the binding specificity of PBF-2. This structural arrangement also supports the role of PBF-2 in binding melted promoter regions to modulate gene expression.
