MA1-724 detects GCAP-1 from human, non-human primate and bovine samples. This antibody is specific for GCAP-1 and does not react with other isotypes.
MA1-724 has been successfully used in Western blot procedures. By Western blot, this antibody detects a ~23 kDa protein representing GCAP-1 protein on bovine rod outer segment membranes.
The MA1-724 immunogen is bacterial expressed full length GCAP-1.
Guanylate cyclase-activating proteins (GCAPs) are calcium binding proteins that belong to the calmodulin superfamily. GCAPs without calcium are responsible for activation of photoreceptor guanylate cyclase during light adaptation. Studies have shown that the addition or subtraction of Ca2+ results in major conformational changes and the activation/deactivation of GCAP-1 and GCAP-2.
It has been demonstrated that both GCAP-1 and 2 act on guanylate cyclase similarly and have approximately 50% homology between the two forms. GCAP-1 (GenBank AF172707) is predominantly localized in the photoreceptor outer segments, while GCAP-2 is found in retina samples.
