Analysis of the ANP receptor subtypes by affinity labeling has shown that a bovine pulmonary aortic endothelial cell line ( CPAE cells ) primarily expresses ANP R 1 ( R , receptor ) coupled to particulate guanylate cyclase , while Hela cells from human cervical carcinoma predominantly express ANP R 2 , which lacks a guanylate cyclase . alpha hANP could bind to both ANP receptor subtypes with high affinity , while MetSO alpha hANP showed more selective binding to ANP R 2 than to ANP R 1 . 0.50527574^^^

Stimulation of guanylyl cyclase A ( GC A ) by atrial natriuretic peptide ( ANP ) is antagonized by activators of protein kinase C ( PKC ) . ^^^ Here , we have developed stable GC A transfectants of NIH3T3 cells , which display marked reductions in hormone dependent cGMP elevations and guanylyl cyclase activity after incubation with ANP or phorbol 12 myristate 13 acetate ( PMA ) . ^^^ The specific PKC inhibitor , GF 109203X , completely blocked the PMA dependent dephosphorylation and desensitization of GC A but failed to inhibit either ANP dependent process . ^^^ Tryptic phosphopeptide maps of GC A isolated from ANP or PMA treated cells were unique , suggesting that the sites that dephosphorylated in response to each agent were different . ^^^ In contrast to previous reports , we conclude that PMA and ANP desensitization of GC A are distinct events mediated by dephosphorylation of specific residues through PKC dependent and independent pathways , respectively . . ^^^
