Predicted to enable microtubule binding activity. Involved in regulation of protein localization. Acts upstream of or within several processes, including anterograde synaptic vesicle transport; generation of neurons; and protein localization to axon. Located in axon initial segment and proximal neuron projection. Orthologous to human TRIM46 (tripartite motif containing 46). [provided by Alliance of Genome Resources, Apr 2022]
