What's a GeneRIF?

Data suggest that structures of active sites of CYP2A1 and CYP2A2 have certain amount of flexibility and that non-specific binding (i.e., hydrophobic binding) is involved in differences in substrate specificity between these two enzymes.

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.
