Aberrant fragment of Dab1 protein is present in yotari mouse.

The Reelin-Dab1 pathway plays important roles in the development of central nervous system. In the autosomal recessive mutant mouse yotari, there is a replacement of a part of Dab1 gene with a long interspersed nuclear element fragment, and it was previously suggested that no protein derived from this gene was present. We here show that an aberrant fragment of Dab1 protein (p64/60) is present in the brain of yotari mouse. The amount of p64/60 is relatively abundant in the embryonic stages and decreased in the postnatal ones. Unlike wild-type Dab1 protein, p64/60 is not phosphorylated by Fyn kinase and localizes considerably to the nucleus. These data suggested that some phenotypes of yotari may be attributable to the presence of p64/60. It also raises a caveat that a tissue from yotari is not a perfect control for immunostaining of Dab1 protein. Copyright © 2014 Elsevier Ireland Ltd and the Japan Neuroscience Society.
