Development of the digestive system forms the mesentery proper. The ventral mesentery, located in the region of the terminal part of the esophagus, the stomach and the upper part of the duodenum, is derived from the septum transversum. Growth of the liver into the mesenchyme of the septum transversum divides the ventral mesentery into the lesser omentum, extending from the lower portion of the esophagus, the stomach, and the upper portion of the duodenum to the liver and the falciform ligament, extending from the liver to the ventral body wall. Development of the digestive system The development of the digestive system concerns the epithelium of
Calponin 3, acidic Calponin 3, acidic Calponin 3. acidic is a protein that in humans is encoded by the "CNN3" gene. The "CNN3" gene is located at 1p22-p21 in the human chromosomal genome. "CNN3" gene contains 7 exons and encodes calponin 3, a 36.4-kDa protein consisting of 329 amino acids with isoelectric point (pI) of 5.84. Calponin 3 is known as acidic calponin. Among three isoforms of calponin, less is known for the gene regulation and function of calponin 3. Nonetheless, much has been learned from extensive studies on the homologous genes "CNN1" and "CNN2" that encode calponin 1 and calponin 2. "CNN3"
