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   -!- SUBUNIT: Cross-linked by interchain disulfide bonds around the DNA-
CC       helix. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus. Chromosome.
CC   -!- TISSUE SPECIFICITY: Testis.
CC   -!- SIMILARITY: Belongs to the protamine P1 family. {ECO:0000305}.
