Predicted to enable iron ion binding activity. Predicted to be involved in iron ion transport. Predicted to be part of intracellular ferritin complex. Human ortholog(s) of this gene implicated in basal ganglia disease; hyperferritinemia-cataract syndrome; neurodegeneration with brain iron accumulation 3; and neurodegenerative disease. Orthologous to human FTL (ferritin light chain). [provided by Alliance of Genome Resources, Apr 2022]
