A new type of ANP receptor system which clearly distinguishes natriuretic peptides A and B (ANP and BNP) has been identified in the human adrenal tumor cell line SW-13 and characterized. SW-13 cells responded to nanomolar concentrations of ANP with large increases in cGMP levels but in the case of BNP, much higher concentrations were required to produce the same extent of response. This property is unique since the 140-kDa ANP receptors so far characterized do not discriminate between ANP and BNP. For comparison, various natriuretic peptide receptors were also re-characterized using the recently identified CNP.
