Molecular cloning and functional expression of the guinea pig cardiac Na(+)-Ca2+ exchanger
Abstract
The cDNA of the guinea pig cardiac Na(+)-Ca2+ exchanger was cloned from a lambda ZAP cDNA library. The deduced sequence of the protein corresponds to 970 amino acids and is 98% identical to the canine cardiac exchanger. The leader peptide region shows substantial variation among species. The cloned cDNA can induce Na(+)-Ca2+ exchange activity when in vitro transcribed cRNA is injected into Xenopus laevis oocytes.
