Plant Cyclophilins: Multifaceted Proteins With Versatile Roles.

Area of Science:

• Plant molecular biology
• Biochemistry
• Cellular processes

Background:

• Cyclophilins are ubiquitous proteins binding cyclosporin A (CsA).
• Many cyclophilins exhibit peptidyl-prolyl cis-trans isomerase (PPIase) activity, crucial for protein folding.
• Plant cyclophilin gene families are significantly expanded compared to other organisms.

Purpose of the Study:

• To review the diverse roles of cyclophilins in plant cellular processes.
• To explore the molecular mechanisms underlying cyclophilin functions in plants.
• To highlight the versatility and importance of cyclophilins in plant growth and development.

Main Methods:

• Literature review of recent studies on plant cyclophilins.
• Analysis of cyclophilin involvement in hormone signaling and stress response pathways.
• Discussion of molecular mechanisms of cyclophilin action.

Main Results:

• Cyclophilins regulate numerous plant growth and development processes.
• These proteins are involved in hormone signaling and stress responses.
• Plant cyclophilins exhibit multiple functionalities beyond PPIase activity.

Conclusions:

• Cyclophilins are essential regulators of diverse physiological pathways in plants.
• Understanding plant cyclophilins offers insights into cellular processes and stress adaptation.
• Further research is needed to fully elucidate the roles of expanded plant cyclophilin families.
