Predicted to enable tubulin binding activity and tubulin-glutamic acid ligase activity. Predicted to be involved in microtubule cytoskeleton organization and protein polyglutamylation. Predicted to act upstream of or within microtubule bundle formation; microtubule severing; and positive regulation of cilium movement. Predicted to be located in 9+0 non-motile cilium and ciliary basal body. Predicted to be active in cilium. Orthologous to human TTLL6 (tubulin tyrosine ligase like 6).
