Guanylyl cyclase-activating protein (GCAP) is thought to mediate Ca(2+)-sensitive regulation of guanylyl cyclase (GC), a key event in recovery of the dark state of rod photoreceptors following light exposure. Here, we characterize GCAP from several vertebrate species by molecular cloning and provide evidence that GCAP contains a heterogeneously acylated(More)
We cloned the guanylate cyclase activating proteins, GCAP1 and GCAP2, from chicken retina and examined their expression in normal and predegenerate rdlrd chicken retina. Northern analyses show that the amounts of the single transcripts encoding GCAP1 and GCAP2 are reduced to about 70% of normal levels in rdlrd retina. Western analyses reveal that GCAP2(More)
