GUCA1B

Chr 6

guanylate cyclase activator 1B

Also known as: GCAP 2, GCAP-2, GCAP-II, GCAP2, GUCA2, RP48

The protein encoded by this gene is a calcium-binding protein that activates photoreceptor guanylate cyclases. This gene may have arisen due to a gene duplication event since there is a highly similar gene clustered with it on chromosome 6. Mutations in this gene can cause a form of retinitis pigmentosa.
