What's a GeneRIF?

Data suggest that substrate specificity of protein farnesyltransferase (subunits Fnta plus Fntb) is extensive; these results expand the scope of the potential prenylated proteome in this species. (Fnta = farnesyltransferase CAAX box alpha protein; Fntb = farnesyltransferase CAAX box beta protein)

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.
