Histone to protamine transition

WebbGene ID: 7141, updated on 29-Mar-2024. Summary. Transition protein-1 is a spermatid-specific product of the haploid genome which replaces histone and is itself replaced in the mature sperm by the protamines (see PRM1, MIM 182880; PRM2, MIM 182890) (Luerssen et al., 1990 [PubMed 2249851]).[supplied by OMIM, Mar 2008] http://genesdev.cshlp.org/content/27/15/1635.full.pdf
