Predicted to enable cyclosporin A binding activity; peptidyl-prolyl cis-trans isomerase activity; and ribonucleoprotein complex binding activity. Predicted to be involved in positive regulation of viral genome replication; protein folding; and protein peptidyl-prolyl isomerization. Predicted to be located in nuclear speck. Predicted to be part of U4/U6 snRNP and U4/U6 x U5 tri-snRNP complex. Predicted to be active in cytoplasm and intracellular membrane-bounded organelle. Is expressed in several structures, including central nervous system; extraembryonic component; and retina. Orthologous to human PPIH (peptidylprolyl isomerase H).
