Domain

Heat shock protein Hsp33, C-terminal (IPR016154)

Short name: Heat_shock_Hsp33_C

Domain relationships

None.

Description

This entry represents the C-terminal alpha/beta domain from the heat shock protein Hsp33. Hsp33 is a molecular chaperone, distinguished from all other known chaperones by its mode of functional regulation. Its activity is redox regulated. Hsp33 is a cytoplasmically localised protein with highly reactive cysteines that respond quickly to changes in the redox environment. Oxidizing conditions like H2O2 cause disulphide bonds to form in Hsp33, a process that leads to the activation of its chaperone function [PMID: 10025400].
