What's a GeneRIF?

Data show that expression levels of tapasin and the immunoproteasome components MECL-1, PA28-alpha, and PA28-beta are lower in Ad12- than in Ad5-transformed BRK cells.

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.
