Enables integrin binding activity and peptidyl-prolyl cis-trans isomerase activity. Involved in platelet aggregation. Acts upstream of or within neuron differentiation. Located in extracellular space and myelin sheath. Is expressed in several structures, including early conceptus; gonad; hemolymphoid system gland; liver; and skeletal muscle. Human ortholog(s) of this gene implicated in cholangiocarcinoma and human immunodeficiency virus infectious disease. Orthologous to human PPIA (peptidylprolyl isomerase A).
