Predicted to enable microtubule binding activity. Predicted to be involved in several processes, including axonal transport; positive regulation of insulin secretion involved in cellular response to glucose stimulus; and regulation of synaptic activity. Predicted to act upstream of or within regulation of insulin secretion involved in cellular response to glucose stimulus. Predicted to be located in dense body; intracellular membrane-bounded organelle; and microtubule. Predicted to be active in cytoplasmic microtubule and vesicle. Is expressed in alimentary system; central nervous system; dorsal root ganglion; and sensory organ. Orthologous to human SYBU (syntabulin). [provided by Alliance of Genome Resources, Apr 2022]
