By copying the passage from a seven year old source, the meaning of "recently" is somewhat stretched.

[It is well known that one major regulatory] mechanism in cell proliferation and transformation is phosphorylation of proteins on serine or threonine residues preceding proline (pSer/Thr- Pro) by various prodirected protein kinases, such as MAP kinases, cyclin-dependent kinases, JNK, and GSK3β. Interestingly, the pSer/Thr-Pro motifs in proteins exist in two completely distinct cis and trans conformations, whose conversion is normally restrained by phosphorylation, but catalyzed specifically by the essential prolyl isomerase Pin1. By isomerizing pSer81, Pin1 induce conformational changes in androgen receptor. This, phosphorylation- dependent prolyl isomerization is a critical mechanism in phosphorylation signaling. One major regulatory mechanism in cell proliferation and transformation is phosphorylation of proteins on serine or threonine residues preceding proline (pSer/Thr- Pro) by various prodirected protein kinases, such as MAP kinases, cyclin-dependent kinases, JNK, and GSK3β.1–3 Interestingly, the pSer/Thr-Pro motifs in proteins exist in two completely distinct cis and trans conformations, whose conversion is normally restrained by phosphorylation, but catalyzed specifically by the essential prolyl isomerase Pin1.3–6 By isomerizing specific pSer/Thr-Pro bonds, Pin1 has been shown to catalytically induce conformational changes in proteins after phosphorylation, thereby having profound effects on their catalytic activity, dephosphorylation, protein-protein interactions, subcellular location, and/or turnover.4,5,7–18 Thus, phosphorylation- dependent prolyl isomerization is a critical postphosphorylation regulatory mechanism in phosphorylation signaling.3
