Heat shock factor binding protein 1 (HSBP1) is a nuclear localized hydrophobic repeat-containing protein, which interacts with trimerization domain of HSF1 and negatively regulates DNA-binding activity of HSF1. Overexpression of HSBP1 in mammalian cells represses the transactivation activity of HSF1 (Satyal SH et al. 1998).
