Predicted to enable Hsp90 protein binding activity; chaperone binding activity; and prostaglandin-E synthase activity. Predicted to be involved in several processes, including cellular protein-containing complex assembly; prostaglandin biosynthetic process; and telomere maintenance via telomerase. Predicted to be active in cytosol and nucleus. Orthologous to human PTGES3 (prostaglandin E synthase 3). [provided by Alliance of Genome Resources, Apr 2022]
