Regulation and physiological functions of phoenixin

Area of Science:

• Neuroendocrinology
• Molecular Biology
• Physiology

Background:

• Phoenixin is a recently identified neuropeptide derived from small integral membrane protein 20.
• It acts as a ligand for G protein-coupled receptor 173 (GPR173) and is found across various species and tissues.
• Initially linked to reproductive functions, its roles have expanded significantly.

Purpose of the Study:

• To review and summarize the latest research on the physiological functions of phoenixin.
• To highlight the broad spectrum of phoenixin's biological activities.
• To assess the potential of phoenixin as a target for novel drug development.

Main Methods:

• Literature review of recent scientific publications on phoenixin.
• Analysis of studies investigating phoenixin's involvement in various physiological processes.
• Examination of research on phoenixin's interaction with other signaling molecules like nesfatin-1.

Main Results:

• Phoenixin's functions extend beyond reproduction to include appetite regulation, memory, Alzheimer's disease, anxiety, inflammation, and cardiovascular function.
• It influences neuronal and microglial activity, energy metabolism, and body fluid balance.
• An interaction between phoenixin and nesfatin-1 has been identified.

Conclusions:

• Phoenixin is a pleiotropic neuropeptide with a wide range of physiological effects.
• Its multifaceted roles position it as a promising candidate for future therapeutic interventions.
• Further research into phoenixin's mechanisms could lead to novel drug development and clinical applications.
