Enables several functions, including beta-catenin binding activity; peptidyl-prolyl cis-trans isomerase activity; and phosphoprotein binding activity. Involved in several processes, including negative regulation of amyloid-beta formation; protein peptidyl-prolyl isomerization; and protein stabilization. Acts upstream of or within regulation of cell population proliferation and regulation of cytokinesis. Located in cytosol and nucleus. Is expressed in several structures, including 2-cell stage embryo; gut; nucleus pulposus; and reproductive system. Used to study Alzheimer's disease. Orthologous to human PIN1 (peptidylprolyl cis/trans isomerase, NIMA-interacting 1). [provided by Alliance of Genome Resources, Apr 2022]
