A 23aa peptide sequence within the ~N-terminal, cytoplasmic domain of rat NCX1 (KLH). Species Sequence Homology: 100%-mouse, canine, feline, 95%-human, rabbit, monkey, bovine, 86%-chicken, 73%-frog.
Ca2+ plays a critical role in intracellular signaling. Intracellular Ca2+ levels are tightly controlled by continuous removal of Ca2+ via ATP-driven Ca2+ pump in the endoplasmic reticulum and plasma membrane, and Ca2+ transport system, the Na+/Ca2+ exchangers (NCX), in the plasma membrane. NCX can move Ca2+ either into or out of cells, depending on the net Na+, Ca2+, and K+ gradient across the membrane. In most cells, 3 Na+ are exchanged for 1 Ca2+. In mammals, at least 5 distinct genes code for the exchangers: Three NCX (NCX1, NCX2, and NCX3), and two in the NCKX family (NCKX1 and NCKX2). NCX share significant sequence homology (~70%), display 11 TM domains, a large central, intracellular hydrophilic regulatory loop between TM5 and 6, extracellular N-terminus and cytoplasmic C-terminus. The N-terminal signal peptide is cleaved off from the mature exchanger protein. Applications: Suitable for use in ELISA. Western Blot, though not tested, may potentially be used as an application. Other applications not tested. Recommended Dilution: ELISA: 0.5-1ug/ml. Control peptide can be used to coat ELISA plates at 1ug/ml. See catalog N0560-20L: NCX1, Rat, Control Peptide (Sodium Calcium Exchanger). Western Blot: 1-10ug/ml using ECL. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
