1. Guanylate cyclase plays an important role in the visual cycle. Here we report the mRNA expression for the atrial natriuretic peptide receptor type A form of guanylate cyclase (ANPRA) in human retina.

2. Polymerase chain reaction using two sets of primers on the cDNAs reverse-transcribed from human retinal poly(A)+ RNA amplified two products under two different reaction conditions. The primers used in the reaction were designed from the reported sequence of human placental ANPRA cDNA.

3. Sequencing of the amplified products showed 100% sequence homology to the human placental ANPRA gene. Northern blot analysis indicated the presence of a 4.4-kb ANPRA mRNA in human retina, similar to that present in human brain.
