dimerization/docking (D/D) domain found in IQ domain-containing protein K (IQCK) and similar proteins IQ motif-containing proteins may play an active role in cell polarization and migration, and even in ciliary function. Although its function remains unclear, IQCK contains a conserved region that shows high sequence similarity to the dimerization/docking (D/D) domains of regulatory subunit of cAMP-dependent protein kinase (PKA) and protein DPY-30/SDC1.
