HSP70: 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 ²¹.

Table 2 lists various pro- and eukaryotic HSP70s together with their alternate names. Among them, Hsp70-1 (UniProt ID #P08107), also known as Hsp70, HspA1, Hsp72 and Hsp70i, is among the first and most prominent HSPs found in stressed cells and has been newly termed HspA1A.
