HSF
From RiceWiki
Brief Introduction
- Heat shock transcription factors (HSFs) play an important role in the physiological response to heat stress by regulating the expression of heat-responsive genes during the initial stages of heat stress [1][2][3][4][5]. They are the primary molecules responsible for rapid relaying signals of cellular stress to the transcriptional apparatus and activating the expression of the HSP genes[4].
Figure 1. Gene Structure of Os05g0530400 - HSFs have a modular structure with a highly conserved HSF domain consisited of a helix-turn-helix(H2-T-H3) motif in the N-terminal region. Connnected to the Cterminal activation domain is an adjacent domain with heptad hydrophobic repeats A/B involved in oligomerization, a nuclear localization signal. After that located a lysine residues serving as nuclear localization signal(NLS), which is required for nuclear import[2][4][5].
