Insight into the biochemical and cell biological function of an intrinsically unstructured heat shock protein, Hsp12 of Ustilago maydis.

ABSTRACT: Small heat shock proteins (sHsps) play diverse roles in the stress response and maintenance of cellular functions. The Ustilago maydis genome codes for few sHsps. Among these, Hsp12 has previously been demonstrated to be involved in the pathogenesis of the fungus by our group. In the present study we further investigated the biological function of the protein in the pathogenic development of U. maydis. Analysis of the primary amino acid sequence of Hsp12 in combination with spectroscopic methods to analyse secondary protein structures revealed an intrinsically disordered nature of the protein. We also carried out detailed analysis on the protein aggregation prevention activity associated with Hsp12. Our data suggest Hsp12 has trehalose-dependent protein aggregation prevention activity.
