Sequences of Gillicthys mirabilis and human Urotensin II: relationships to oxytocin, vasopressin and somatostatin.^a

^aSequence identities between Gillichthys mirabilis and human Urotensin II and either human somatostatin 14 or oxytocin and arginine vasopressin are indicated by the bold, grey-shaded underlined sequences. The homology between Gillichthys and human UII is denoted by amino acids represented in bold type in human UII. The cysteines (C^*) are shown to be joined by a disulphide bridge (superscript asterisks), forming a 6-member ring in UII, oxytocin and vasopressin and a 12-member ring in somatostatin. Amino acids are designated by their one-letter codes (A = alanine, R = arginine, etc.).
