Human digestive system Human digestive system The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The process of digestion has many stages. The first stage is the cephalic phase of digestion which begins with gastric secretions in response to the sight and smell of food. The next stage starts in the mouth. Chewing, in which food is mixed with saliva, begins the mechanical process of digestion. This produces
Calponin 3, acidic in mouse CC myoblasts inhibited cell fusion during "in vitro" differentiation, whereas "Cnn3" gene knockdown promoted cell fusion and the expression of skeletal muscle myosin. The inhibitory effect of calponin 3 was reversed upon phosphorylation by Rho-associated kinase 1/2 (ROCK1/2). 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.
