Predicted to enable GTPase activator activity and beta-tubulin binding activity. Predicted to be involved in several processes, including cell-cell junction assembly; post-chaperonin tubulin folding pathway; and tubulin complex assembly. Predicted to be located in centrosome. Predicted to be active in lateral plasma membrane. Orthologous to human TBCD (tubulin folding cofactor D). [provided by Alliance of Genome Resources, Apr 2022]
