Nuclear basic proteins in sperm of Xenopus laevis consist of 6 sperm-specific proteins (SPs1–6) in addition to somatic core histones. Using a cDNA for SP4 as a probe, we cloned genomic DNA containing SP4 genes from a genomic library constructed from recombinant λ bacteriophage containing 12.0 kbp- E...
