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 regulation of blastocyst development. Predicted to be located in 9+0 non-motile cilium and ciliary basal body. Predicted to be active in cilium. Orthologous to human TTLL4 (tubulin tyrosine ligase like 4). [provided by Alliance of Genome Resources, Apr 2022]
