Description
Heat shock factor (HSF) is a transcriptional activator of heat shock genes [1, 4]: it binds specifically to heat shock promoter elements, which are palindromic sequences rich with repetitive purine and pyrimidine motifs [1]. Under normal conditions, HSF is a homo-trimeric cytoplasmic protein, but heat shock activation results in relocalisation to the nucleus [2]. Each HSF monomer contains one C-terminal and three N-terminal leucine zipper repeats [3]. Point mutations in these regions result in disruption of cellular localisation, rendering the protein constitutively nuclear [2]. Two sequences flanking the N-terminal zippers fit the consensus of a bi- partite nuclear localisation signal (NLS). Interaction between the N- and C-terminal zippers may result in a structure that masks the NLS sequences: following activation of HSF, these may then be unmasked, resulting in relocalisation of the protein to the nucleus [3]. The DNA-binding component of HSF lies to the N terminus of the first NLS region, and is referred to as the HSF domain.
