Immunohistochemical localization of calcium-activated neutral protease (CANP) in rabbit organs was determined using a monoclonal antibody against CANP. In most organs, epithelial tissues reacted intensely: these tissues include great alveolar and squamous alveolar cells in lung; interlobular artery, vein, and bile duct in liver; small vessels in skeletal muscle; glomeruli, juxtanglomerular cells, distal and collecting tubules in kidney; mucous epithelium in gallbladder; interstitial cells in testis; and cuboidal epithelial cells in brain choroid plexus. On the other hand, hepatocytes, epithelial cells which have ill defined basal lamina, were stained very faintly. These observations suggest that the physiological function of CANP is involved with transport systems in epithelial tissues through basal lamina.

D002154 Calpain Cysteine proteinase found in many tissues. Hydrolyzes a variety of endogenous proteins including NEUROPEPTIDES; CYTOSKELETAL PROTEINS; proteins from SMOOTH MUSCLE; CARDIAC MUSCLE; liver; platelets; and erythrocytes. Two subclasses having high and low calcium sensitivity are known. Removes Z-discs and M-lines from myofibrils. Activates phosphorylase kinase and cyclic nucleotide-independent protein kinase. This enzyme was formerly listed as EC 3.4.22.4.

D004847 Epithelial Cells Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
