It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.
Acts as a regulatory subunit for serine/threonine-protein phosphatase 2A (PP2A) modulating its activity or substrate specificity, probably by inducing a conformational change in the catalytic subunit, a proposed direct target of the PPIase.
Can reactivate inactive phosphatase PP2A-phosphatase methylesterase complexes (PP2A(i)) in presence of ATP and Mg(2+) (By similarity).
Reversibly stimulates the variable phosphotyrosyl phosphatase activity of PP2A core heterodimer PP2A(D) in presence of ATP and Mg(2+) (in vitro).
The phosphotyrosyl phosphatase activity is dependent of an ATPase activity of the PP2A(D): PPP2R4 complex.
Is involved in apoptosis; the function appears to be independent from PP2A.
