Results describe three atomic structures of RIO2 kinase showing that it forms homodimer in vitro. Upon self-association, each protomer ATP-binding pocket is partially remodeled. The homodimerization is mediated by key residues previously shown to be responsible for ATP binding and catalysis. This data reveals an intricate mechanism where identical residues are involved in substrate binding and oligomeric state formation.

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.
