Urotensin II (UTS2) is a highly conserved neuropeptide belonging to the vasoactive peptide family, initially isolated from the teleost fish neuroendocrine system. In humans, it is encoded by the *UTS2* gene located on chromosome 1p36 and expressed in the central nervous system, cardiovascular tissues, kidneys, and other organs. UTS2 binds specifically to the G protein-coupled receptor UT (UTS2R), triggering diverse cellular responses. It exhibits potent vasoactive properties, influencing blood pressure regulation, inflammation, and metabolic processes. While it can act as a vasodilator or vasoconstrictor depending on context, its dysregulation is linked to cardiovascular diseases (e.g., heart failure, atherosclerosis), metabolic syndrome, and renal dysfunction.
Recombinant human UTS2 protein is produced using bacterial (e.g., *E. coli*) or mammalian expression systems, ensuring high purity and bioactivity for research applications. It serves as a critical tool for studying UTS2-UTS2R signaling pathways, drug screening, and exploring therapeutic strategies targeting urotensinergic systems. Despite its pathological roles in chronic diseases, UTS2 also demonstrates cytoprotective effects in acute stress conditions, highlighting its complex dual nature. Current studies focus on developing UT receptor modulators to balance its pleiotropic effects, offering potential treatments for hypertension, diabetes, and fibrotic disorders.
