comparison of g-proteins in muscle membrane fractions with g-proteins isolated from bovine brain and human erythrocyte as well as their reaction with antisera to either a common sequence of alpha subunits of g-proteins ( g alpha common antibody ) or to a unique sequence of the alpha subunit of go ( g alpha o antibody ) indicated that the two lower molecular weight bands in cardiac sl are go or go-like , and therefore the upper band is probably gi .
