dimerization/docking (D/D) domain found in RIIa domain-containing protein 1 (RIIAD1) and similar proteins
The family includes uncharacterized RIIa domain-containing protein 1 (RIIAD1), which contains a C-terminal domain that shows high sequence similarity to the dimerization/docking (D/D) domain of regulatory subunit of cAMP-dependent protein kinase (PKA).
