Summary
Protamines substitute for histones in the chromatin of sperm during the haploid phase of spermatogenesis, and are the major DNA-binding proteins in the nucleus of sperm in many vertebrates. They package the sperm DNA into a highly condensed complex in a volume less than 5% of a somatic cell nucleus. Many mammalian species have only one protamine (protamine 1); however, a few species, including human and mouse, have two. This gene encodes protamine 2, which is cleaved to give rise to a family of protamine 2 peptides. Alternatively spliced transcript variants have also been found for this gene.

NCBI Reference Sequences (RefSeq)

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

    See identical proteins and their annotated locations for NP_001273285.1

    Status: REVIEWED

    Description
    Transcript Variant: This variant (2) uses an alternate acceptor splice site at the last exon that causes a frameshift compared to variant 1. The resulting isoform (2) has a longer and distinct C-terminus compared to isoform 1.

RNA

  1. NR_104428.1 RNA Sequence

    Status: REVIEWED

    Description
    Transcript Variant: This variant (6) is alternatively spliced at the 3' end compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
