Predicted to enable RNA polymerase II CTD heptapeptide repeat P3 isomerase activity; RNA polymerase II CTD heptapeptide repeat P6 isomerase activity; and calcium ion binding activity. Predicted to be located in endoplasmic reticulum. Human ortholog(s) of this gene implicated in Ehlers-Danlos syndrome kyphoscoliotic type 2. Orthologous to human FKBP14 (FKBP prolyl isomerase 14).
