PPIL1 (Peptidylprolyl Isomerase Like 1): PPIL1 is a member of the cyclophilin family of enzymes that catalyze the cis-trans isomerization of proline bonds in proteins, aiding in protein folding and assembly. This activity supports key cellular processes such as signal transduction, transcription regulation, and cell cycle control. PPIL1 contributes to maintaining cellular balance and stress response by participating in protein complexes and helping splice pre-mRNA for accurate gene expression.
