A 22aa Peptide sequence within the cytoplasmic domain 3 of rat NCX2 (1) was selected for antibody production. Ca2+ plays a critical role in intracellular signaling. Intracellular Ca2+ levels are tightly controlled by continuos 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. NCX1 (rat 971 aa, human 970 aa, mouse 970 aa) is most prominently expressed in the heart where it plays a major role in excitation-contraction coupling, but is also present in most other tissues. Alternative spicing of NCX1/NACA1 produces numerous tissue specific isoforms (heart NACA1, Kidney NACA2, -3, and -7, brain NACA4-6). NCX2 (rat 921 aa) is restricted to brain and skeletal muscle. NCX3 (rat 927 aa) shares 73-75% with NCX1 and NCX2. NCX3 is also restricted to brain and muscle.
