In an earlier study (Kimura, Y., Kurzydlowski, K., Tada, M., and MacLennan, DH (1997) J.
Biol. Chem. 272, 15061–15064), mutation of amino acids on one face of the
phospholamban (PLN) transmembrane helix led to loss of PLN inhibition of sarco (endo)
plasmic reticulum Ca 2+-ATPase (SERCA) molecules. This helical face was proposed to
form a site of PLN interaction with a transmembrane helix in SERCA molecules. To
determine whether predicted transmembrane helices M4, M5, M6, or M8 in SERCA1a …
