Immunological homology was investigated between Heterosigma akashiwo (a marine alga) Na + ‐activated ATPase and animal Na + ,K + ‐ATPase. The former polypeptide [(1989) Plant Cell Physiol. 30, 923‐928] reacted with anti‐serum raised against the amino‐terminal half of the pig kidney Na + ,K + ‐ATPase α subunit. It is suggested that the Na + ,K + ‐ATPase epitope within the amino‐terminal region is conserved in the plant Na + ‐activated ATPase, and the region containing the epitope may be important for Na ion transport.
