Notes |
Low activity determined by the Neu1a allele occurs in the SM/J inbred strain and in wild mice in the area of Ann Arbor, Michigan; all other inbred strains have high activity determined by the Neu1b allele. Heterozygotes have intermediate activity. Neuraminidase removes extra sialic acid residues from these enzymes. The defective neuraminidase of Neu1a> mice, by failing to remove the extra sialic acid, changes their electrophoretic mobility (J:6480). Level of activity of neuraminidase in activated T lymphocytes is also depressed in Neu1a/Neu1a mice (J:7976).
