AC MF_02000; DC Protein; auto TR HAMAP; MF_02000; -; 1; level=0 XX Names: HSP20_IbpA XX ID IBPA DE RecName: Full=Small heat shock protein IbpA; DE AltName: Full=16 kDa heat shock protein A; GN Name=ibpA; XX CC -!- FUNCTION: Associates with aggregated proteins, together with IbpB, to CC stabilize and protect them from irreversible denaturation and extensive CC proteolysis during heat shock and oxidative stress. Aggregated proteins CC bound to the IbpAB complex are more efficiently refolded and CC reactivated by the ATP-dependent chaperone systems ClpB and CC DnaK/DnaJ/GrpE. Its activity is ATP-independent. CC -!- SUBUNIT: Monomer. Forms homomultimers of about 100-150 subunits at CC optimal growth temperatures. Conformation changes to monomers at high CC temperatures or high ionic concentrations. CC -!- SUBCELLULAR LOCATION: Cytoplasm. CC -!- SIMILARITY: Belongs to the small heat shock protein (HSP20) family.
