Abstract excerpt
In this study, an enzymatic inactive mutant of GnT-V (delta cGnT-V) was constructed and transfected in SMMC 7721 cell line. Integrin beta1 in delta cGnT-V transfectants (delta c-7721) showed attenuation of the number of beta1-6 GlcNAc branching, whereas those in wtGnT-V transfectants (wt-7721) presented a beta1-6 GlcNAc-rich pattern. High integrin beta1 expression was observed in wt-7721 compared with mock cells...
