HSP90: Alternate Names

The progressive expansion of the heat shock (stress) protein field has led to inconsistencies and a lack of clarity in the nomenclature for these families of molecules. As a consequence, Kampinga and colleagues have proposed new guidelines to encourage the use of consistent and clear terminology ²⁵. Table 2 lists various pro- and eukaryotic HSP90s together with their alternate names. Among them, Hsp90α1 (UniProt ID #P07900; also known as HspC1, Hsp90AA1) and Hsp90β (UniProt ID #08238; also known as HspC3, Hsp90AB1) are among the most prominent HSP90s found in stressed and non-stressed cells.
