What's a GeneRIF?

PGK2 is expressed differently in the testes of mouse and pigs according to developmental stage.
Title: Species-specific expression of phosphoglycerate kinase 2 (PGK2) in the developing porcine testis.
These results identify multiple signaling and metabolic defects that are likely contributors to male infertility and the absence of progressive sperm motility seen in mice lacking GAPDHS.
Title: Sperm function, protein phosphorylation, and metabolism differ in mice lacking successive sperm-specific glycolytic enzymes.
Data from studies in transgenic mice suggest that Pgk2 core promoter elements are required to direct demethylation of DNA and reconfiguration of nucleosomes in testis during sexual maturation and spermatogenesis.
Title: Sequence-specific promoter elements regulate temporal-specific changes in chromatin required for testis-specific activation of the Pgk2 gene.
not required for the completion of spermatogenesis, but essential for sperm motility and male fertility
Title: Phosphoglycerate kinase 2 (PGK2) is essential for sperm function and male fertility in mice.
t-KH-type splicing regulatory protein binds directly to a 93-nt sequence (designated the F1 region) of the 3'-UTR of the Pgk2 mRNA and destabilizes Pgk2 mRNA constructs in testis extracts.
Title: A cytoplasmic variant of the KH-type splicing regulatory protein serves as a decay-promoting factor for phosphoglycerate kinase 2 mRNA in murine male germ cells.
Pgk2 crystal structures have been solved; the apoenzyme is in the "open" form; that is, the N-terminal domain that can bind 3-phosphoglycerate and the C-terminal domain that binds ATP are too far apart for the substrates to interact.
Title: X-ray analysis of phosphoglycerate kinase 2, a sperm-specific isoform from Mus musculus.
Data suggest that binding of PBX4, plus its coactivator PREP1, is a rate-limiting step leading to the initiation of tissue-specific transcription of the Pgk2 gene.
Title: In vivo analysis of developmentally and evolutionarily dynamic protein-DNA interactions regulating transcription of the Pgk2 gene during mammalian spermatogenesis.
PTBP2 is a trans-acting factor that helps to stabilize Pgk2 mRNA in male mouse germ cells.
Title: Polypyrimidine tract binding protein 2 stabilizes phosphoglycerate kinase 2 mRNA in murine male germ cells by binding to its 3'UTR.

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.
