Abstract

The phosphorylation sites of the myelin basic protein from bovine brain were determined after phosphorylation with a cyclic 3′:5′-phosphate-dependent protein kinase from the same source. Three phosphorylated peptides were selectively rapidly separated, before and after dephosphorylation, by reversed-phase high-performance liquid chromatography on a styrene 250 column under alkaline conditions. Partial sequencing of the peptides by automated Edman degradation revealed that the serine-115 residue located in the main encephalitogenic determinant of the protein was a phosphorylation site, in addition to the two phosphorylation sites established (threonine-34 and serine-55).
