What's a GeneRIF?

Differential phosphorylation of IPS isoforms in brain, intestine and testis suggests novel functions in these tissues.
Title: Rat brain myo-inositol 3-phosphate synthase is a phosphoprotein.
Isyna1 is regulated, in part, by DNA methylation and that significant alterations in methylation patterns during development could have a major impact on inositol phosphate synthase expression in later life.

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.
