Enables microtubule binding activity. Involved in several processes, including microtubule bundle formation; positive regulation of microtubule polymerization; and positive regulation of nitrogen compound metabolic process. Located in cytoplasm; midbody; and spindle. Is expressed in several structures, including brain ventricular layer; lung; rest of cerebellum marginal layer; submandibular gland primordium; and thymus primordium. Orthologous to human PSRC1 (proline and serine rich coiled-coil 1). [provided by Alliance of Genome Resources, Apr 2022]
