Glycosylated forms of nuclear lamins

AbstractChromatin and pore complex-lamina preparations were obtained from pig and chicken tissues, and their proteins were analysed by mono- and bidimensional electrophoresis. A glycosylated form of lamin A, recognized by concanavalin A, was shown to be present in at least 3 of the tissues examined. Glycosylation is suggested to be a further postsynthetic modification, besides phosphorylation and methylation, which can modify the properties of lamins
