Enables peptidyl-prolyl cis-trans isomerase activity. Predicted to be involved in several processes, including regulation of neuron apoptotic process; regulation of protein metabolic process; and regulation of signal transduction. Predicted to be located in several cellular components, including ciliary basal body; mitochondrion; and nucleoplasm. Predicted to be active in glutamatergic synapse; nucleus; and postsynaptic cytosol. Orthologous to human PIN1 (peptidylprolyl cis/trans isomerase, NIMA-interacting 1).
