protein
DEFINITION:
Any of a group of complex organic compounds which contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur, the characteristic element being nitrogen, and which are widely distributed in plants and animals. Proteins, the principal constituents of the protoplasm of all cells, are of high molecular weight and consist essentially of combinations of a-amino acids in peptide linkages. Twenty different amino acids are commonly found in proteins, and each protein has a unique, genetically defined amino acid sequence which determines its specific shape and function. They serve as enzymes, structural elements, hormones, immunoglobulins, etc., and are involved in oxygen transport, muscle contraction, electron transport, and other activities throughout the body, and in photosynthesis.
binding protein - any of a number of plasma proteins (See below) that bind to hormones of low solubility (chiefly the thyroid and steroid hormones), thus providing a transport system for them; some are specific for particular hormones, while others bind to any sparingly soluble hormones. Called also carrier protein or transport protein (See below).
carrier proteins - A binding protein (See above).
plasma proteins - The hundreds of different proteins present in blood plasma, including carrier proteins (such as albumin, transferrin, and haptoglobin), fibrinogen and other coagulation factors, complement components, immunoglobulins, enzyme inhibitors, precursors of substances such as angiotensin and bradykinin, and many other types of proteins.
transport protein - binding protein (See above).

Translocation of the Aquaporin-2 (AQP2) water channel to and from the apical membrane is regulated by the antidiuretic hormone vasopressin (AVP). In states of hypernatremia or hypovolemia, binding of AVP to its type 2 receptor increases cAMP concentration through the activation of adenylate cyclase. Increases in the intracellular cAMP concentration results in the activation of PKA, leading to the phosphorylation of three to four monomers of the AQP2 homotetramer and the translocation of AQP2 to the apical membrane. Regulation of protein routing and expression involves the recognition of motifs in these proteins by interacting protein complexes. Recently we identified a first and novel protein of 42 kDa, which interacted with the C-terminal tail of AQP2 and which we named Aquaporin-2 maturing protein 1 (AMP1). Immunohistochemistry on kidney sections revealed that AMP1 and AQP2 were co-expressed in the same cells. Yeast-2-hybrid analysis showed that AMP1 interacted with the tail of AQP2, AQP2-S256A and AQP2-S256D, but not with those of AQP3 or AQP4. To unravel its function, AMP1 was co-expressed in wt10 cells, which are Madin Darby Canine Kidney (MDCK) cells, in which AQP2 is translocated from intracellular vesicles to the plasma membrane upon treatment with forskolin. Co-expression with AMP1 interfered with the forskolin-induced translocation of AQP2, which was not observed for AQP4. Furthermore, AMP1 was shown to reduce the expression of AQP2 in several clones. The decrease in AQP2 expression and disturbed sorting of AQP2 to the apical membrane as found with AMP1 expression are as found in acquired NDI. As such, AMP1 might have important role in the regulation of AQP2 in these forms of NDI.
