Predicted to enable metal ion binding activity. Predicted to be involved in plus-end-directed vesicle transport along microtubule and positive regulation of autophagosome maturation. Predicted to be located in Golgi apparatus. Predicted to be active in autophagosome; late endosome; and lysosome. Is expressed in central nervous system; early conceptus; and retina. Human ortholog(s) of this gene implicated in cataract 18. Orthologous to human FYCO1 (FYVE and coiled-coil domain autophagy adaptor 1). [provided by Alliance of Genome Resources, Apr 2022]
