GCAP3 Products

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. Disease research has linked this protein with cone dystrophy, neuronitis, and retinitis. This protein has shown interactions with GUCA1A, GUCA1B, GUCY2D, GUCY2F, and CNGA3 proteins in the pathways such as the visual cycle in retinal rods, olfactory transduction, and phototransduction pathways.
