Enables alpha-tubulin binding activity and beta-tubulin binding activity. Involved in several processes, including cellular response to hydrostatic pressure; response to cocaine; and response to desipramine. Located in several cellular components, including axon terminus; neuronal cell body; and perinuclear region of cytoplasm. Biomarker of glaucoma and mental depression. Human ortholog(s) of this gene implicated in Lewy body dementia. Orthologous to human SNCG (synuclein gamma). [provided by Alliance of Genome Resources, Apr 2022]
