Replacement of DNA-binding histones by protamines results in nuclear chromatin condensation and is essential for correct differentiation of round spermatids into mature spermatozoa and male fertility (reviewed in Steger, 1999; Steger et al., 2003).Interestingly, protamine-1 is present in spermatozoa from all species …
WebbThis pathway is known for its importance in pre-fertilization sperm events. In summary, a novel hypothesis for gradual histone-to-protamine transition in sperm maturation was proposed. We believe that histones may contribute structural information into early embryo by epigenetically modifying centromeric chromatin and other types of repetitive DNA.
