Predicted to be involved in negative regulation of dendrite development and neuron migration. Predicted to act upstream of or within several processes, including negative regulation of axon extension involved in regeneration; positive regulation of SMAD protein signal transduction; and response to auditory stimulus. Predicted to be located in early endosome. Predicted to be active in cytoplasmic vesicle and plasma membrane. Orthologous to human KIAA0319 (KIAA0319); INTERACTS WITH 6-propyl-2-thiouracil; bisphenol A; endosulfan.
