Docking experiments suggested a pivotal role of Arg-635 at the entrance of the binding pocket in HCN2, either causing stabilizing cation-pi interactions with the aromatic ring in N (6)-Phe-cAMP or N (6)-Bn-cAMP or a steric clash with the aromatic ring in N (6)-Bnz-cAMP.
Title: N(6)-modified cAMP derivatives that activate protein kinase A also act as full agonists of murine HCN2 channels.

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.
