| - | [[http://www.uniprot.org/uniprot/PTPA1_YEAST PTPA1_YEAST]] PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Acts as a regulatory subunit for TAP42-associated PP2A-like phosphatases modulating their activity or substrate specificity, probably by inducing a conformational change in the catalytic subunit, a direct target of the PPIase. Can reactivate inactive phosphatase PP2A-phosphatase methylesterase complexes (PP2Ai) in presence of ATP and Mg(2+) by dissociating the inactive form from the complex. Involved in the regulation of cell cycle progression, mitotic spindle formation, bud morphogenesis and DNA repair.<ref>PMID:11262194</ref> <ref>PMID:11134337</ref> <ref>PMID:12952889</ref> <ref>PMID:15150670</ref> <ref>PMID:15689491</ref> <ref>PMID:16380387</ref> | ||
