- * 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)-D-R-I-x(3)-S-x(2)-G-C
- [The two 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.
