Mv. Lemas et Dm. Fambrough, SEQUENCE-ANALYSIS OF DNA ENCODING AN AVIAN NA-ATPASE BETA-2-SUBUNIT(,K+), Biochimica et biophysica acta, 1149(2), 1993, pp. 339-342
The DNA encoding a chicken Na+,K+-ATPase beta2-subunit was cloned and
sequenced. The deduced amino acid sequence has structural features com
mon to all known Na+,K+-ATPase beta-subunits. It is proposed to belong
to the beta2-isoform family, though the amino acid sequence has signi
ficantly diverged from mammalian beta2-subunit sequences. Similar to o
ther Na+,K+-ATPase beta2-isoforms, the chicken beta2-isoform mRNA is p
redominantly expressed in brain tissue.
