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 (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Chromosome {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Testis.
CC   -!- SIMILARITY: Belongs to the protamine P1 family. {ECO:0000305}.
