Urocortin II, a neuropeptide hormone within the corticotropin-releasing factor (CRF) family—which comprises mammalian CRF, urocortin I, urocortin III, frog sauvagine, and piscine urotensin I—displays 34, 43, and 37-40% sequence homology with rat and human CRF, human urocortin I, and human urocortin III, respectively. This compound enhances rabbit ventricular myocyte shortening and relaxation in both a time- and concentration-dependent manner. In vivo studies reveal that urocortin II lowers arterial blood pressure in both normotensive and spontaneously hypertensive rats through peripheral CRF2 receptor agonism, inducing dose-dependent tachycardia and hypotension at doses of 3 and 30 pmol/kg. Additionally, it mitigates the visceral pain response to colorectal distension at 10 and 20 μg/kg in conscious rats and delays gastric emptying in mice.

Urocortin II is a neuropeptide hormone and member of the corticotropin-releasing factor (CRF) family which includes mammalian CRF , urocortin , urocortin III , frog sauvagine, and piscine urotensin I.1 Mouse urocortin II shares 34 and 42% sequence homology with rat CRF and urocortin . It is expressed in mouse paraventricular, supraoptic, and arcuate nuclei of the hypothalamus, the locus coeruleus, and in motor nuclei of the brainstem and spinal ventral horn. Urocortin II selectively binds to CRF1 over CRF2 receptors (Kis = 0.66 and >100 nM, respectively) and induces cAMP production in CHO cells expressing CRF2 (EC50 = 0.14 nM). In vivo, urocortin II suppresses nighttime food intake by 35% in rats when administered intracerebroventricularly at a dose of 1 μg. Urocortin II (0.1 and 0.5 μg, i.c.v) stimulates fecal pellet output, increases distal colonic transit, and inhibits gastric emptying in mice.2References1. Reyes, T.M., Lewis, K., Perrin, M.H., et al.

It is also selective for cGAS over toll-like receptors (TLRs) at 50 μM.
