Function
Roles in the folding of β-propeller proteins, such as Gβ1, in addition to its major target proteins, actin and tubulin. Interacts with chaperonin type BBSs, including BBSs 6, 10, and 12. Mutations in CCT2 could lead to genetic retinal diseases (27645772). Mutations in the CCT2 gene is causative for severe syndromic retinopathies or non-syndromic retinal dystrophies such as Leber congenital amaurosis (LCA) (40103630).

Finally, CCDC181 is identified as a interacting protein for CCTβ protein, and its localization to photoreceptor connecting cilia is compromised in the mutant mouse.
