Tnp2 transition protein 2 [Rattus norvegicus (Norway rat)] - Gene

Summary

Official Symbol: Tnp2provided by RGD
Official Full Name: transition protein 2provided by RGD
Primary source: RGD:3885
See related: AllianceGenome:RGD:3885
Gene type: protein coding
RefSeq status: PROVISIONAL
Organism: Rattus norvegicus
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Rattus
Summary: Enables zinc ion binding activity. Predicted to be involved in several processes, including penetration of zona pellucida; positive regulation of protein processing; and sperm DNA condensation. Predicted to act upstream of or within binding activity of sperm to zona pellucida and flagellated sperm motility. Is active in nucleus. Orthologous to human TNP2 (transition protein 2).

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.
