Cloning of the rat heart Na(+)-Ca2+ exchanger and its functional expression in HeLa cells.

abstract：:Ubiquitin was extracted from testis of 4 mammals and purified to homogeneity by gel filtration chromatography. Amino acid compositions and NH2-terminal sequences were found to be identical in the 4 species and with calf thymus ubiquitin. Ubiquitin conformation was shown to be very sensitive to oxidation. Improved meth...
