Enables microtubule binding activity. Involved in several processes, including cellular response to nerve growth factor stimulus; negative regulation of cardiac muscle cell proliferation; and regulation of glutamate metabolic process. Located in several cellular components, including axonal growth cone; cell body fiber; and lateral plasma membrane. Part of protein-containing complex. Colocalizes with neuron projection and synapse. Used to study anemia; colon adenocarcinoma; colon cancer; and familial adenomatous polyposis. Human ortholog(s) of this gene implicated in several diseases, including carcinoma (multiple); endometrial cancer (multiple); familial adenomatous polyposis 1; hereditary desmoid disease; and medulloblastoma. Orthologous to human APC (APC regulator of WNT signaling pathway). [provided by Alliance of Genome Resources, Apr 2022]
