NPR

National Public Radio (NPR) is a privately and publicly funded non-profit membership media organization that serves as a national syndicator to a network of 900 public radio stations in the United States.

NPR produces and distributes news and cultural programming. Individual public radio stations are not required to broadcast all NPR programs that are produced. Most public radio stations broadcast a mixture of NPR programs, content from rival providers American Public Media, Public Radio International and Public Radio Exchange, and locally produced programs. NPR's flagships are two drive time news broadcasts, Morning Edition and the afternoon All Things Considered; both are carried by most NPR member stations, and are two of the most popular radio programs in the country.

NPR manages the Public Radio Satellite System, which distributes NPR programs and other programming from independent producers and networks such as American Public Media and Public Radio International. Its content is also available on-demand via the web, mobile, and podcasts.

NPR1

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).

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

NPR3

Natriuretic peptide receptor C/guanylate cyclase C (atrionatriuretic peptide receptor C), also known as NPR3, is an atrial natriuretic peptide receptor. In humans it is encoded by the NPR3 gene.

Function

The family of natriuretic peptides elicit a number of vascular, renal, and endocrine effects that are important in the maintenance of blood pressure and extracellular fluid volume. These effects are mediated by specific binding of the peptides to cell surface receptors in the vasculature, kidney, adrenal, and brain.
