CD23, the low affinity IgE receptor, is hypothesized to function as a negative regulator of IgE production. Upon discovering reduced CD23 surface levels in 129/SvJ inbred mice, we sought to further investigate 129/SvJ CD23 and to examine its influence on IgE levels. Five amino acid substitutions were found in 129/SvJ CD23. Identical mutations were also observed in CD23 from New Zealand Black and 129P1/ReJ mice....
