Other Info
| About the antigen | Pepsinogen II also known as progastricsin or PGC(pepsinogen C), is an aspartic protease expressed primarily in gastric chief cells and is a novel marker of type 2 cells with advantages over many of the current markers used to identify type 2 cells in the developing lung. It is involved in proteolysis and peptidolysis. This protein has 2 isoforms produced by alternative splicing. |
| More Information | Pepsinogen consists of a single polypeptide chain of 375 amino acids with an average molecular weight of 42 kD. PG I (isoenzyme 1-5) is secreted mainly by chief cells in the fundic mucosa, whereas PG II (isoenzyme 6-7) is secreted by the pyloric glands and the proximal duodenal mucosa. Precursor reflects numbers of stomach surface cells as well as glandular cells, and monitors gastric atrophy indirectly. They are also extraordinarily stable because they perform their jobs under the harsh conditions present in the digestive system. The atrophy of the corpus mucosa leads to low synthesis of pepsinogen I and hence its low release into the serum. Serum pepsinogen I indicates function and states of gastric mucosa.  |
