A novel strategy to identify maternal and paternal inheritance in the mouse.
A novel strategy for identifying proteins which reveal maternal or paternal inheritance in the mouse is presented. Using two-dimensional electrophoresis we investigated protein expression patterns of adult liver and different embryonic and extraembryonic tissue in C57BL/6Crl and in DBA/2Crl mice, as well as in their reciprocal hybrids. We found three groups of protein spots which showed maternal or paternal inheritance of quantitative variations. These proteins were characterized by N-terminal or internal amino acid sequencing, by determination of the amino acid composition, by glycoprotein staining and RNA expression analysis. The three proteins identified were: alpha-enolase, cyclophilin and beta-group hemoglobins. The parental effects observed for alpha-enolase and cyclophilin were found to be due to parent-specific post-translational modifications of these proteins. For the beta-group hemoglobins our results suggested parental effects on the transcriptional level.
