Predicted to enable GTP binding activity and identical protein binding activity. Predicted to be a structural constituent of cytoskeleton. Acts upstream of or within meiotic spindle organization. Located in several cellular components, including condensed nuclear chromosome; microtubule cytoskeleton; and non-motile cilium. Is expressed in several structures, including eye; heart; nervous system; notochord; and respiratory system. Human ortholog(s) of this gene implicated in complex cortical dysplasia with other brain malformations 4; inclusion body myositis; and muscular disease. Orthologous to human TUBG1 (tubulin gamma 1).
