{PDOC00236} {PS00263; NATRIURETIC_PEPTIDE} {BEGIN} ********************************** * Natriuretic peptides signature * ********************************** Atrial natriuretic peptides (ANP) [1,2,3] are vertebrate hormones important in the overall control of cardiovascular homeostasis and sodium and water balance in general. There are various ANP peptides which vary in length but which have a common central core; they are all processed from a single precursor. There is a disulfide bond which is important for the expression of the biological activity. The ANP protein family includes three additional structurally related peptides which elicit a pharmacological spectrum similar to ANP: - Brain natriuretic peptide (BNP). - C-type natriuretic peptide (CNP). - Ventricular natriuretic peptide (VNP) [4]. - Green mamba natriuretic peptide (DNP) [5]. The signature developed for the ANP family includes the two cysteines involved in the disulfide bond and two conserved glycines which may be important for the conformation of the peptides. -Consensus pattern: C-F-G-x(3)-[DEA]-[RH]-I-x(3)-S-x(2)-G-C [The 2 C's are linked by a disulfide bond] -Sequences known to belong to this class detected by the pattern: ALL. -Other sequence(s) detected in Swiss-Prot: NONE. -Last update: December 2004 / Pattern and text revised.
