Proteases are primarily secreted in the stomach and the pancreas. In the stomach, the enzyme pepsin is secreted by gastric cells in an inactive form and activated by stomach acid to aid in protein digestion. The pancreas secretes various proteases, such as trypsin and chymotrypsin, into the small intestine, where they continue the process of protein breakdown into smaller peptides and amino acids.
Endopeptidases are typically produced and secreted by various cells in the body, such as pancreatic acinar cells and gastric chief cells, as well as by certain microorganisms. These enzymes play a critical role in protein digestion by cleaving peptide bonds within the interior of protein molecules.
Proteases are secreted in their inactive forms so as to prevent self-digestion and the destruction of the body's own cells. This is because all cells have proteins and hence are susceptible to the catabolic effects of proteases. However, amylase is not secreted in an inactive form as we do not store starch in our cells, but rather, we store carbohydrates in the form of glycogen. Therefore amylase poses no risk to our cells. Lipase-secreting cells also do not contain lipids and therefore lipase poses no threat to the body's own cells.
The opposite of DNA would be non-DNA, such as RNA, which is another nucleic acid that plays a role in protein synthesis and gene regulation in cells.
Leptin is primarily secreted by adipose tissue (fat cells) and acts as a hormone in the regulation of body weight and energy balance. It is not secreted by a specific endocrine gland like the thyroid or pancreas.
Keratin is a tough, waterproofing protein. Keratin is secreted by the cells of the epidermis (the outermost layer of skin).
Interferon is a small protein secreted by virus-infected cells that plays a key role in the body's defense against viruses. Interferon helps to prevent viral replication and spread to neighboring cells by activating the immune response.
A gonadotrophin is any of a group of protein hormones secreted by gonadotrope cells of the pituitary gland of vertebrates.

Rennin or chymosin is secreted in the fourth stomach of a cow. See the related link for more information.
Two mechanisms of protein regulation in eukaryotic cells are post-translational modifications, such as phosphorylation or glycosylation, that can alter protein activity, stability, or localization. Another mechanism is protein degradation through the ubiquitin-proteasome system, which targets proteins for degradation when they are tagged with ubiquitin.
Proteins do most of the work in cells. Proteins are required for the structure, function, and regulation of the bodyâ??s tissues and organs.

Leptin is a protein that is secreted from adipose (fat) cells. It acts on receptors in the Central Nervous System and other sites to induce energy expenditure and inhibit food intake (Margetic et al. 2002).
