Two-dimensional Electrophoretic Protein Patterns of Reciprocal Hybrids of the Mouse Strains DBA and C57BL
Overview
Affiliations
Two-dimensional electrophoretic patterns of cytoplasmic liver proteins of the mouse were investigated in reciprocal hybrids of the two inbred mouse strains DBA and C57BL in order to establish whether strain-specific protein variants reveal a mode of inheritance compatible with the concept of genomic imprinting. Variants of this type were found to account for about 11% of approximately 200 variant protein spots scrutinized. Transmission of the maternal form of a variant protein was more frequent than transmission of the paternal form. Maternal/paternal transmission was observed only for proteins showing strain variations in their amount. The results are discussed in terms of the frequency of imprinted genes.
