NPR1

For the gene in A. thaliana, see Arabidopsis thaliana § NPR1.

Not to be confused with NPR One.

Natriuretic peptide receptor A/guanylate cyclase A (atrionatriuretic peptide receptor A), also known as NPR1, is an atrial natriuretic peptide receptor. In humans it is encoded by the NPR1 gene.

Function

NPR1 is a membrane-bound guanylate cyclase that serves as the receptor for both atrial and brain natriuretic peptides (ANP and BNP, respectively).^[5]

It is localized in the kidney^[6] where it results in natriuresis upon binding to natriuretic peptides. However, it is found in even greater quantity in the lungs and adipocytes.^[6]
