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:0000250|UniProtKB:P07978}.
CC   -!- SUBUNIT: Interacts with TDRP. {ECO:0000250|UniProtKB:P07978}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P07978}.
CC       Chromosome {ECO:0000250|UniProtKB:P07978}.
CC   -!- TISSUE SPECIFICITY: Testis.
CC   -!- PTM: Proteolytic processing into mature chains is required for histone
CC       eviction during spermatogenesis. Transition proteins (TNP1 and TNP2)
CC       are required for processing. {ECO:0000250|UniProtKB:P07978}.
CC   -!- SIMILARITY: Belongs to the protamine P2 family. {ECO:0000305}.
