31. Recent studies have revealed a functional link between AUF1, heat shock proteins and the ubiquitin-proteasome network. 32. RNA motif is involved in heat shock regulation. 33. The heat shock protein 70 ( Hsp70 ) family contains both heat-inducible and constitutively expressed members. 34. Its expression is induced by heat shock . 35. Heat shock protein HSP27 was shown to be one of the substrates of this kinase in vivo.36. Heat shock proteins, as a class, are among the most highly expressed cellular proteins across all species.37. The heat shock 70 kDa protein 8 also known as Hsc70 belongs to the heat-shock cognate subgroup. 38. FKBP5 has been shown to interact with Heat shock protein 90kDa alpha ( cytosolic ), member A1. 39. Heat shock protein 90 ( Hsp90 ) is one of the most common of the heat-related proteins.40. ERN1 has been shown to interact with Heat shock protein 90kDa alpha ( cytosolic ), member A1.
