General Information

General Information Comment Organism
malfunction isozyme GnT-IVb deficiency shows mild phenotypic alterations in hematopoietic cell populations and hemostasis, GnT-IVa/-IVb double deficiency completely abolishes GnT-IV activity that results in the disappearance of the GlcNAcbeta1-4 branch on the Manalpha1-3 arm Mus musculus
