Urotensin I TFA（Cat No.:I044315）is a synthetic form of Urotensin I, a peptide hormone originally identified in fish and structurally related to corticotropin-releasing factor (CRF). In mammals, Urotensin I functions as a neuropeptide that binds to CRF receptors, influencing stress responses, cardiovascular regulation, and neuroendocrine signaling. It exhibits vasodilatory and diuretic effects and plays a role in modulating behavior and hormone secretion. The TFA (trifluoroacetate) salt form enhances peptide solubility and stability. Urotensin I is widely used in neurobiology, endocrinology, and cardiovascular research to study CRF-related signaling pathways.
