Key role of PIN1 in telomere maintenance and oncogenic behavior in a human glioblastoma model.

PIN1 is the only known enzyme capable of recognizing and isomerizing the phosphorylated Serine/Threonine‑Proline motif. Through this mechanism, PIN1 controls diverse cellular functions, including telomere maintenance. Both PIN1 overexpression and its involvement in oncogenic pathways are involved in several cancer types, including glioblastoma (GBM), a lethal disease with poor therapeutic resources.
