| Biochem/physiol Actions: | Guanylate cyclase activator 2A (GUCA2A) is mainly an intestinal peptide hormone and endogenous ligand of guanylyl cyclase C. It is produced as prohormone proguanylin. In the intestine, GUCA2A along with guanylate cyclase C receptor activates epithelial cells. Activation of this pathway results in secretion of Cl- and HCO3- and inhibition of Na+ absorption, which drives water secretion into the intestinal lumen. In the renal tissue GUCA2A elicits natriuresis, kaliuresis, and diuresis, along with increasing urinary cyclic guanosine monophosphate (cGMP) levels. GUCA2A is suggested to elevate the exrection of urinary salt and water, which results in the prevention of hypernatremia and hypervolemia following increased salt uptake by the body. The protein is also expressed in epithelial cells of the ductal system of human parotid and submandibular glands. It is released into the saliva through salivary duct cells. GUCA2A is highly expressed in salivary gland tumors. On the other hand, GUCA2A is down-regulated in colorectal cancer. |

| Features and Benefits: | Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section. Every Prestige Antibody is tested in the following ways: • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues. • Protein array of 364 human recombinant protein fragments. |
| General description: | The gene guanylate cyclase activator 2A (GUCA2A) is mapped to human chromosome 1p35-p34. GUCA2A mRNA is mainly detected in the gastrointestinal tract and kidney. |
