Abstract
β-1,4-galactosyltransferase 1 (β1,4-GT 1) is the key enzyme transferring galactose to the terminal N-acetylglucosamine (GlcNAc) forming Galβ1→4GlcNAc structure in the Golgi apparatus. In addition, it also serves as a cell adhesion molecule by recognizing and binding to terminal GlcNAc of glycoconjugates on the adjacent cell surface and matrix through a subpopulation of the enzyme distributed on the cell surface. Transient expression of the p58GTA protein kinase, which belongs to the p34cdc2-related supergene family, could enhance β1,4-GT 1 total activity in COS cells. In this study, the p58GTA interaction with β1,4-GT 1 was confirmed using an in vitro assay with the TNT® Coupled Reticulocyte Lysate System. An expression vector containing p58GTA was stably transfected into 7721 cells, a human hepatocarcinoma cell line, expression was confirmed by Northern and Western blot analyses. The cells transfected with p58GTA (p58GTA/7721) contained 1.9 times higher total β1,4-GT 1 activity and 2.6 times higher cell-surface β1,4-GT 1 activity than the mock transfected cells (pcDNA3/7721). However, Ricinus communis agglutinin-I lectin blot analysis revealed that the enhanced β1,4-GT 1 activity did not increase the Galβ1→4GlcNAc groups on most of the membrane proteins in p58GTA/7721 cells. By flow cytometry analysis, it was found that the p58GTA/7721 cells were G2/M phase arrested, compared with the pcDNA3/7721 cells. These results suggest that the p58GTA stable transfection into human hepatocarcinoma cells could enhance the two β1,4-GT 1 subcellular pool activities independently and change its cell-cycle without modifying the β-1,4-linked galactose residues on most membrane proteins.
