PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides (By similarity). Histone chaperone possibly involved in H3/H4 deposition to the nucleosome. Associates with 18S rDNA chromatin and negatively regulates the level of its expression.By similarity1 Publication
