Predicted to enable GTP binding activity; identical protein binding activity; and protein domain specific binding activity. Predicted to be a structural constituent of cytoskeleton. Involved in regulation of synapse organization. Located in cytoplasmic microtubule. Is active in neuromuscular junction. Is expressed in several structures, including brain; hemolymphoid system gland; lateral plate mesoderm; liver; and testis. Used to study congenital nervous system abnormality and lissencephaly. Human ortholog(s) of this gene implicated in lissencephaly; lissencephaly 3; microcephaly; and visual epilepsy. Orthologous to human TUBA1A (tubulin alpha 1a).
