OX NCBI_TaxID=10100 {ECO:0000313|EMBL:ACP41673.1}; RN [1] {ECO:0000313|EMBL:ACP41673.1} RP NUCLEOTIDE SEQUENCE. RX PubMed=19364735; DOI=10.1098/rspb.2009.0257; RA Martin-Coello J., Dopazo H., Arbiza L., Ausio J., Roldan E.R., Gomendio M.; RT "Sexual selection drives weak positive selection in protamine genes and RT high promoter divergence, enhancing sperm competitiveness."; RL Proc. R. Soc. B 276:2427-2436(2009). CC -!- FUNCTION: Protamines substitute for histones in the chromatin of sperm CC during the haploid phase of spermatogenesis. They compact sperm DNA CC into a highly condensed, stable and inactive complex. CC {ECO:0000256|RuleBase:RU000650}. CC -!- SUBCELLULAR LOCATION: Chromosome {ECO:0000256|ARBA:ARBA00004286}. CC Nucleus {ECO:0000256|RuleBase:RU000650}. CC -!- SIMILARITY: Belongs to the protamine P1 family. CC {ECO:0000256|ARBA:ARBA00008957, ECO:0000256|RuleBase:RU000650}.
