Predicted to enable microtubule binding activity. Involved in several processes, including chemotaxis; cilium assembly; and hyperosmotic response. Located in cilium; dendrite; and neuronal cell body. Expressed in amphid neurons and phasmid neurons. Used to study ciliopathy. Human ortholog(s) of this gene implicated in Joubert syndrome. Is an ortholog of human TOGARAM1 (TOG array regulator of axonemal microtubules 1) and TOGARAM2 (TOG array regulator of axonemal microtubules 2).
