21. AHSA1 has been shown to interact with Heat shock protein 90kDa alpha ( cytosolic ), member A1. 22. Heat shock proteins , as a class, are among the most highly expressed cellular proteins across all species.23. Heat shock protein 90 ( Hsp90 ) is one of the most common of the heat-related proteins.24. Recent studies have revealed a functional link between AUF1, heat shock proteins and the ubiquitin-proteasome network. 25. They produce heat shock proteins , but unlike other animals they do this not in direct response to heat. 26. For example, actin, the ATPase domain of the heat shock protein , and hexakinase together form a superfamily. 27. Heat shock protein 47 has been shown to interact with collagens I, II, III, IV and V.28. Heat shock factor 1 ( HSF-1 ) is the major regulator of heat shock protein transcription in eukaryotes. 29. The protein encoded by this gene was originally suggested to be a member of the heat shock protein 70 family. 30. SMYD3 has been shown to interact with Heat shock protein 90kDa alpha ( cytosolic ), member A1 and POLR2A.
