GCAP3 Proteins and Enzymes

GCAP3, also known as GUCA1C or Guanylyl cyclase-activating protein 3, has a 209 amino acid isoform that is 24 kDa and a short 196 amino acid isoform that is approx. 22 kDa; commonly found in retina; in conditions of low free calcium ions concentration stimulates guanylyl cyclase 1 (GC1) and GC2 and when the concentration is elevated inhibits guanylyl cyclases, which is very important for the recuperation of the dark state of rod photoreceptors following light exposure.
