Possible role of cortactin phosphorylation by protein kinase Cα in actin-bundle formation at growth cone.

abstract：:Using gold labelled neoglycoproteins containing either alpha-D-glucose, N-acetyl-beta-D-glucosamine, alpha-D-mannose, 6-phospho-alpha-D-mannose, and alpha-L-fucose (BSA), we investigated their intranuclear binding sites in the TG human cell line. Although gold-labelled BSA did not give any noticeable labelling, the pr...
