Abstract excerpt
In our recent analyses [1] of five tandemly arranged genes encoding a major sperm-specific basic nuclear protein (SP4) of Xenopus laevis, we found a gene containing a single base substitution which will give rise to the replacement of the 69th residue among the 78 amino acids of SP4. In this study, the polypeptide from sperm nuclei which were separated by reversed-phase HPLC as a distinct entity from SP4 were...
