Abstract:Protamine 2 (Prm2/PRM2), together with Protamine 1 (Prm1/PRM1), constitute the two protamines found in both murine and human sperm. During spermiogenesis in haploid male germ cells, chromatin undergoes significant condensation, a phase in which most histones are replaced by a species-specific ratio of these two protamines. Altered PRM1/PRM2 ratios are associated with subfertility and infertility in both male mice and men. Notably, during histone-to-protamine exchange a small fraction of histones remains (rangi… Show more
