Proteolytic patterns of R8. Equal amounts of R8 were incubated with either trypsin or papain for indicated times. Lanes 1–5 are nonphosphorylated and lanes 6–10 are phosphorylated R8. Arrow indicates intact R8. Sequences of indicated proteolytic fragments are: (●) GIRKFS1; (*)RQSVLNLM; and (○)SVNQGQNI.
