Predicted to enable cullin family protein binding activity. Predicted to be involved in several processes, including cytoplasmic sequestering of NF-kappaB; regulation of I-kappaB kinase/NF-kappaB signaling; and vesicle-mediated transport to the plasma membrane. Predicted to be located in endosome. Human ortholog(s) of this gene implicated in Ritscher-Schinzel syndrome 2. Orthologous to human CCDC22 (coiled-coil domain containing 22).
