Summary: Enables cyclosporin A binding activity and peptidyl-prolyl cis-trans isomerase activity. Involved in ascospore formation and positive regulation of meiotic nuclear division. Located in mitochondrial intermembrane space and nucleus. Part of Set3 complex. Human ortholog(s) of this gene implicated in cholangiocarcinoma and human immunodeficiency virus infectious disease. Orthologous to several human genes including PPIA (peptidylprolyl isomerase A). [provided by Alliance of Genome Resources, Dec 2024]
