<jats:p>The Na+,K(+)-ATPase alpha subunit has three known isoforms, alpha 1, alpha 2 and alpha 3, each encoded by a separate gene. This study was undertaken to determine the functional status of a fourth human alpha-like gene, ATP1AL2. Partial genomic sequence analysis revealed regions exhibiting sequence similarity with exons 3-6 of the Na+,K(+)-ATPase alpha isoform genes. ATP1AL2 cDNAs spanning the coding sequence of a novel P-type ATPase alpha subunit were isolated from a rat testis library. The predicted polypeptide is 1028 amino acids long and exhibits 76-78% identity with the rat Na+,K(+)-ATPase alpha 1, alpha 2 and alpha 3 isoforms, indicating that ATP1AL2 may encode a fourth Na+,K(+)-ATPase alpha isoform. A 3.9-kb mRNA is expressed abundantly in human and rat testis.</jats:p>
