The mRNA binding-mediated self-regulatory function of small heat shock protein IbpA in γ-proteobacteria is conferred by a conserved arginine.

The Journal of biological chemistry - 1 Sept 2023

Cheng Yajie, Miwa Tsukumi, Taguchi Hideki

Abstract excerpt

Bacterial small heat shock proteins, such as inclusion body-associated protein A (IbpA) and IbpB, coaggregate with denatured proteins and recruit other chaperones for the processing of aggregates thereby assisting in protein refolding. In addition, as a recently revealed uncommon feature, Escherichia coli IbpA self-represses its own translation through interaction with the 5'-untranslated region of the ibpA mRNA,...
